NEW BI-MONTHLY FORMAT ^jMempers SCHOOL OF THOUGHT — THE TIMEX EDUCATION PROGRAM Computer literacy means many different things to many different people. Philosophically TIMEX views computer lit- eracy as , . a working knowledge of the computer which enables the individual to utilize the computer as an extension of his or her own mind... M Putting this philosophy to work requires knowledge of; * The computer and its capabilities * Input, processing, and retrieval routines that manipulate the computer and its data * An elementary (at least) understanding of TIMEX Basic programming * Methods of utilizing prerecorded software The TIMEX Education Program works with the academic community to organize and originate computer literacy cumculums at multi-levels: In public and parochial school districts, on the college campus, for adult education training centers, at computer camps, and through circulation by public library systems. To meet these ambitious goals, a compre- hensive TIMEX Education Program has been developed which includes; * Teacher Training * Teacher Support * Hardware Competency * Administrative Software * Self-teaching Software * Minimal Investment * Fund Raising Activities * Educator s Newsletter Teacher Training — Operating at an educator-to-educator level, the program works in the following manner: A teacher from a school district attends university- based seminars (ranging from 5 to 30- hours) which acquaints the educator with the TIMEX Personal Computer — its fea- tures, concepts and operation. (The teacher receives graduate-level credit and/or in-service credit for each seminar.) Back home, the educator proceeds to train other teachers from the school district. HOW TO GET RID OF BUGS Hopefully, this won’t happen to you! But should your "home-grown" program be bugged by bugs {a bug is an error in a pro- gram such as a wrong character), there's an easy way to utilize the computer to eradicate these pesky characters. EDIT CURSOR - A DEBUGGING AGENT In a previous issue of RAMBLINGS, we discussed five of the cursors that are utilized with the TIMEX Sinclair Personal Computer. However, there's one cursor that we didn't describe, That's the Edit cursor — the topic of this article, Because this cursor is utilized as a “pro- gram editor," smalt changes (i.e., modifying a statement or part of a statement) can be made without disrupting the remainder of the program. This is particularly useful dur- ing the debugging process — especially when a large program is involved. When the Edit cursor is displayed on your television screen, it takes the form of an inverse "greater than” symbol Q We'll illustrate the use of the Edit cursor through the following example: In the program below, Statement 80 contains a bug; the GOTO command should specify Statement 130 instead of 120. Here's how we make the correction: 1 0 PRINT "I AM THINKING OF A’* 90 PRINT ■'NUMBER BETWEEN 1 AND 100 " 30 PflJNT "CAN YOU GUESS IT?" 40 LET A * INT [RND*1 00] +1 50 INPUT B 60 IF A< BTHEN GOTO 90 70 IF A> BTHEN GOTO 110 80 IF A = BTHEN GOTO 120 90 PRINT B: "TOO HIGH" 100 GOTO 50 110 PRINTS: "TOO LOW" 190 GOTO 50 0 30 PRINT B; "CORRECT- PROGRAM WITH A BUG Continued on Page 3 Then, working like a pyramid, computer literacy flows downward from a single edu- cator to many educators and ultimately is spread amongst a great number of students. Teacher Support — Comprehensive educator-level materials help the teacher introduce TIM EX- related computer science into the classroom. These support materL ats include: workbooks (both programming and computer operation), lesson plans, paraphernalia for audio-visual presenta- tions, and CAI software. CAI (Computer Aided instruction) software is an important teacher/pupil aid. Through this mechanism classroom instruction is supplemented by computer-based tute- lage. In addition to stimulating student interest, CAI offers individual instruction, re- inforces new learning skills, and facilitates teacher monitoring of student progress. CAI instruction is provided by more than 30-TIMEX software modules (now under development) in diverse disciplines such as social sciences, language arts, physical sciences, mathematics, and computer science.

REQUEST PERMISSION TO LAND” Let your imagination soar and experience the thrill of flying an airplane — right in the comfort of your own home. The TIMEX Flight Simulator is an educational and fun-filled software cassette that puts you at the controls of a twin-engine, high- performance, propeller-driven airplane. You'll need skill, steady hands, and a knowledge of aerodynamics and naviga- tion {which you'll learn from the software) to fly to and land your plane. Aircraft flight is governed by two aerody- namic principles: lift and forward speed. Lift is created by airflow over the wings of the aircraft, creating lift from below. The extension of the flaps — from the wings — alters the airflow to increase or decrease the amount of lift. Once off the ground, forward speed keeps the aircraft up, in the air. LET'S TAKE OFF Start your engines by entering the com- mand LOAD “FLIGHT” or LOAD " " and press the ENTER key The program loads in about six-minutes and concludes with a load check. If the check indicates that the load failed, please reload the program. To begin your flight, select the appropriate option by answering Y (yes) or N (no) to the options displayed on the screen. * Full Flight * Landing Practice * Wind Effects (recommended only for the experienced pilot). TAKE THE PILOT'S SEAT Once you have taken your seat in the cock- pit, the Instrument Panel, the Navigation Map, the Instrument Landing System (ILS), and the pilot's controls are used to fly to the airport and land on the runway Flying your T/S airplane requires your close attention to the Instrument Panel illustrated and defined below. It will be necessary to pilot the plane along the correct vector {course or compass direction) and the proper heading {compass direction in which the aircraft points) to reach the air- port. Then you will have to bank (turn) the airplane onto the final approach and land the plane at the proper speed, rate of descent, and angle of descent.

Simultaneously press the LIST (K) keys to list the program (the LIST command can be initiated when the K cursor is displayed on the screen). 2, Simultaneously press the SHIFT and the Down Arrow (#6) keys. The Edit cursor is now displayed at the first statement at the top of the screen: 101 20 1 00 “ 30 40 50 60 70 60 90 100 110 120 130 I PRINT 1 PRINT 1 I AM THINKING OF A” NUMBER BETWEEN 1 AND PRINT “CAN YOU GUESS IT?"

When performing Step 3, use the Up Arrow (#7) and SHIFT keys to move the cursor upward. When the cursor is positioned at the appropriate statement, proceed to Step 4, below), {As an alternative to Steps 1 through 3, type the command LIST 60 and press the ENTER key to move directly to the state- ment that is to be edited. Then proceed with Steps 4, 5, and 6, below, 4. Simultaneously press the SHIFT and the EDIT (#1 ) keys to display the statement — to be corrected — at the bottom of the screen: /To PRINT "1 AM THINKING OF A" 20 PRINT "NUMBER BETWEEN 1 ANO 100* 30 PRINT “CAN YOU GUESS IT?" 40 LET A = INT (RND* 1 00) + 1 50 INPUT B 60 IF A< BTHEN GOTO 90 70 IF A>BTHEN GOTO 1 1 0 00 IF A-BTHEN GOTO ISO 90 PRINT B; "TODHIGH” 100 GOTO 50 110 PRINT B; "TOO LOW" 120 GOTO 50 130 PRINT B; "CORRECT" \82 H IF A - B THEN GDTO 1 20 J CURSOR AT BOTTOM OF SCREEN 5. The illustration below demonstrates Step 5, Use the appropriate arrow key (#5^ or #8^) to move the cursor to the position — on the statement line — where the correction is to be made. Then, proceed to type the correction (if necessary the deletion function — SHIFT and 0 keys) can be utilized to make the correction. You may need to move the cursor past the error before making the deletion. The Arrow key can be used to accomplish this. /To PHJNT "1 AM THINKING OF A" N 20 PRINT"NUMBER BETWEEN 1 AND 100" 30 PRINT "CAN YOU GUESS IT?" 40 LET A = INT [RND* 1 00] +1 50 INPUT B 60 IF A < BTHEN GOTO 90 70 IF A > BTHEN GOTO 1 10 @0 IF A = BTHEN GOTO 120 90 PRINT B; 'TOO HIGH- 100 GOT 0 50 110 PRINT 0; "TOO LOW" 120 GOTO 50 130 PRINT B, "CORRECT" \so IF A -BTHEN GOTO 1@0 MOVE CURSOR TO EDIT LOCATION 6.

To run it, copy the program and then press the RUN (R) key When the L cursor appears at the bottom of the screen, simply enter a number (from 1 to 100) until you have guessed the correct answer. Finally the sidebar explains the logic be- hind this program. This explanation may be helpful to the first-time programmer. ANATOMY OF A PROGRAM You might recognize this program as being an expanded version of the one which ap- pears on page 31 of your T/S 1000 User Manual, Statements 10 through 30 are simple print commands. Statement 40 is much more complex. In this statement, we are telling the computer to randomly (RND) select a number (INT; an integer) between 1 and 100 and to store it in a location we shall call A (LET A =). Now, since the computer produces an (in- teger) fractional number (less than 1), we multiply that integer by 100 (RND* 100), And since we want a universe of 100 num- bers, we then add 1 to the random com- mand (RND -100) + 1 Statement 50 tells the computer that we will input certain data (a number) and we want the computer to store this input at a location we shall call B. Statement 60 is a yes/no compare state- ment. We are telling the computer that if the number the computer has stored in loca- tion A is less than the number stored in location B, proceed to carry out the instruc- tion stated in Statement 90; otherwise, go to the next statement (70). Statement 70 is the reverse of Statement 60; //the number the computer has stored in location A is greafer than the number stored in location 8, the computer is to carry out the instruction listed in Statement 110; otherwise, proceed to Statement 80, Statement 80 asks the computer to com- pare the numbers stored in locations A and B, and if they are equal , carry out the instructions specified in Statement 130, Statements 90, 110, and 130 are simple print commands. Note that the (;B) tells the computer to also print the number that was input at the keyboard. Statements 100 and 120 are also compare statements. In effect, they tell the computer that since the number we input was either too high or too low, we will input another number — to try again (at Statement 50). 3 Pilot to Control Tower Continued THE PILOT IS IN CONTROL Several controls are needed to fly your plane. The principle ones — on an actual airplane — are the control stick, flap, throt- tle, and landing gear. For example, moving the control stick side- ways works the ailerons on the wings so the airplane banks to the left or right, as ap- propriate. In asimilar manner, pushing the control stick forwards, or pulling it back- wards manipulates the elevators on the rear of the plane to cause the plane to climb or descend, respectively. Your T/S aircraft is equipped with the follow- ing controls, which simulate those of a typi- cal aircraft of this type. KEY FUNCTION ♦ When pressed, plane loses altitude. ^ When pressed, plane gains altitude. ^ When pressed, plane banks (turns) to the right. ^ When pressed, plane banks (turns) to the left. P When pressed, plane gains airspeed. O When pressed, plane loses airspeed. F When pressed, the flap is lowered, 0 When pressed, the flap is retracted, G When pressed, the landing gear is either lowered or raised. B When pressed, successively dis- plays the ID of each Beacon. M When pressed (when the Instrument Panel is displayed), the current dis- play is erased and the Navigation Map appears; when pressed with the Navigation Map displayed, the Instrument Panel reappears. V When pressed (w hen the Instru ment Panel is displayed), the current dis- play is erased and the ILS appears; when pressed with the ILS dis- played, the Instrument Panel reappears, MAPPING OUT YOUR FLIGHT It is a good idea to use the Navigation Map to travel to the airport. To view the map (when the Instrument Panel is displayed), press the M key on the keyboard. The Navigation Map is illustrated below. On the map you'll find the four points of the compass, the Beacons, the current head- ing of the aircraft, and an aircraft hazard consisting of a series of hills to the East of the runway. These hills rise to an altitude of some 1500-feet above sea level and are lo- cated about 7 V 2 -miles from the runway The position of your plane is shown as a mov- ing, blinking, rectangular light. As you can see, the runway runs on an East-to-West axis; therefore, it will be necessary to bank onto a heading of either 90- or 120-degrees to start your final approach. In order to approach the runway properly, the airplane must gradually descend at an angle of about 3-degrees. This angle of de- scent implies a height of about 6, 000-feet at 20-miles from the runway, 3,000-feet at 10-miles out, and 1 ,000-feet at the SVz-miie mark. You can easily make the height ad- justments “on the fly" At the start of your flight, the computer will randomly select a starting point. From this position, you must find your way to the runway To chart your course, select an Outer Bea- con as a guidepost and press the B key (the Instrument Panel is displayed during this step) until the Beacon ID is displayed {a Beacon is a radio beam which plots the po- sition of the aircraft based on the intensity of the signal). Note the heading in the BRG ‘window" and bank the aircraft until that heading is displayed in the RDF Heading "window” above the RDF Dial. As the aircraft approaches the 90 E / 270 W axis, you will probably need to bank the air- plane to line-up with the runway Do so by selecting the appropriate Inner Beacon (the Inner Beacon is about 2-miles from the run- way) and adjust your heading accordingly Finally, as the Inner Beacon is approached, the heading of the aircraft may need to be slightly adjusted to obtain a more precise alignment with the runway The Runway Beacon (there is no ID designation for this Beacon in the Beacon ID "window") can be utilized to obtain the heading to turn the plane onto its final approach. TOUCHDOWN In a manner analogous to the standard-shift automobile, on which the dutch, shift lever, brake pedal, and steering wheel must all be engaged when stopping the vehicle, full flaps must be applied, the landing gear Continued on Page 5 BUY 2 — GET 2 FREE Here's a special TIMEX 1000 series cas- sette software offer!

For example, at the elementary level, the sturdy T/S 1000 is perfect for inaugurating the computer literacy program. At the next step up-the-ladder, the T/S 1500 with its 16K on-board RAM and typewriter-style, push-button keyboard is more appropriate for the intermediate-level student. At the ad- vanced stage, the larger memory and the greater complexity of the full-color T/S 2068 challenges the skills of the "computer expert" The TIMEX Education Program recom- mends the use of the 1000 series for gram- mar scholars from K to 6th grade, the 1 500 for 7th to 10th graders, and the 2000 series from 11th grade on up. Administrative Software — TIMEX soft- ware also minimizes mundane recordkeep- ing chores associated with teaching and office administration. For the teacher, TIMEX software helps re- duce the amount of time spent on grading, testing, and student evaluations so more hours can be devoted to teaching. In the office, the TIMEX Personal Computer helps alleviate the paperwork burden con- nected with attendance, class scheduling, ^ student and teacher records, and school bus routing and dispatching. Self-Teaching Software — TIMEX CMI (Computer Managed Instruction) encour- ages the strengthening of old skills and the fortification of new ones at the student's own, comfortable, pace. Individual software modules (under development) for SAT preparation, Driver's Education, Word Processing, and Vocational Training offers individualized instruction, immediate feedback, positive reinforcement, and stimulates good study habits — in a no- pressure type of environment. Minimal Investment — One of the very serious concerns in the education commu- nity today revolves around the requirement of funding worthy programs like those for computer literacy. In recognition of these exigencies, a specially price package is available to schools, colleges, computer camps and libraries. So competitive is the TIMEX Education Program offer, an entire com- puter lab for some 20-students can be equipped with TIMEX equipment for less than the price of a single, higher-priced microprocessor. ^ Additionally, fund raising activities can be implemented to minimize the strain upon the school district budget. Fund Raising — Fund raising plans — featuring the TIMEX Personal Computer — have two very big advantages: First, the T/S computer can be purchased by the student or parent for home use to practice skills learned at school, and second, the school earns free computers for use in the classroom. Educator s Newsletter — This quarterly publication is available to all educators in- terested in the TIMEX Educators Program, It Is sponsored and published jointly by the Educators User Group at Texas Wesleyan College and TIMEX. If this school of thought has provided you with food for thought, write for more information (and a subscription to TEC NEWS) to: Dr. Mark Wasicsko Associate Dean School of Education Texas Wesleyan College Fort Worth, TX 76105 Pilot to Control Tower Continued must be lowered, airspeed and altitude must be reduced, and the plane must be aiigned with the runway prior to the landing. When you turn onto the final approach, you'll want to use the Instrument Landing System (ILS) (illustrated below) to achieve a successful touchdown. ARTIFICIAL HORIZON RUNWAY LIGHTS SPEED INDICATOR ILS At the top of the ILS you'll see the horizon (light shaded area). Below it is the runway and its landing lights. As your airplane ap- proaches touchdown, the display moves towards you — just as if you were actually piloting a real plane. On the bottom of the ILS you’ll find the arti- ficial horizon, a speed gage, and a height (Radio Altimeter) indicator. The square gage on the far left-side of the ILS acts as an artificial horizon; it indicates the start of the runway relative to the posi- tion of the plane: The start of the runway is displayed as a flashing light within the gage. If the plane is squarely aligned with the runway, the light will flash in the center of the gage; if the flashing light is at the left- or right-side(s) of the gage, the position of the plane is slightly off -course and should be adjusted before touchdown. When the flashing light is above the gage, the piane is descending too steeply; if below the gage, the plane is not descending steeply enough. Aircraft speed is displayed in the center in- dicator. Reduce airspeed as you land, but do so carefully so the engines won't stall. Finally, the radio altimeter uses a radio- beam reflection system to measure the height of the airplane’s wheels above the runway. This height (in feet) is displayed in the far right indicator on the ILS.

Bob shows us how a temporary program change can be made without losing the original statement. This is accomplished by converting the original statement into a REM as illustrated by the following example: FROM: 410 LET LS>(N) 4 1 50 GOTO 500 * S$( TO 29) 410 REM LET L${N) ■ SS (TO 20) 411 LET L5(N) -S$ (TO 23) 415BGQTQ500 TO: 2391 LET BA = INT {BA*1DD + .1 )/1 00 BUGS AND GREMLINS Because the T/S 1000 series accurately “crunches numbers" to QVz significant digits — of which only 8 are printed — a rounding-off error can inject an incorrect balance into the TIMEX Checkbook Manager software cassette According to David Farmer of Norfolk, Virginia, this bug can easily be corrected by adding the following statement to the program (be sure to make the correction before entering any data). In addition, the TIMEX States and Capitals software cassette also contains a small bug: The capital of Florida, Tallahassee, is spelled with one "e" instead of two. Dave tells us to edit line 8528 to correct the error, PROGRAMMING CAN BE FUN You can duplicate the following programs in the TIMEX Personal Computer to find out just how much fun programming can be We are indebtedto the T/S users identified by the first program REM for submitting the programs to RAM BUNGS.

To the first-time or uniniti- ated computer owner, this "jargon" can be misleading or confusing. Each issue, well list some of the common (and not so common) computer terms. These highly simplified definitions will help you better understand your computer and its "lingo" . Spend a few minutes to learn these terms, and you'll soon be talking like a computer professional. Bug — A bug is an error in a program which causes the program to fail (stop) or causes the program to run in a fashion that does not produce the intended result. A Syntax error, for example, is a type of bug. However, the T/S Personal Computer iden- tifies the Syntax error immediately; you won t spend hours looking for it later. Debugging — Systematic approach to iso- lating — and correcting — bugs in a pro- gram. When a program is debugged, the programmer examines the program — line- by-line — to identify a bug, and then pro- ceeds to edit the program to enter the correction. Report Code — Identifies a bug in a pro- gram. It is signified — at the bottom of the screen — by a number (or letter) and a statement number (indicates the statement at which the program stopped), A list of error (report) codes are listed in the rear of your T/S 1000 User Manual for easy reference. Flowchart — Pictorial diagram to identify all steps of a program. Graphic Characters — Characters used to create a graphical display such as a bar graph or a picture. Resulting graphics can be reproduced on your TV screen or TIMEX Printer Twenty graphics keys — on the T/S 1000 keyboard — can be used to produce the appropriate graphics. Intelligent Terminal — A particular type of terminal which can perform certain func- tions independently of the computer. Since the program is stored in the terminal's memory — instead of in the computer — additional memory is available in the com- puter for other programs and/or data. Keyword — Certain commands which prompt the computer to perform a particu- lar function (i.e. PRINT). The TIMEX Personal Computer offers a unique system of displaying any of the 37-keywords by pressing a single key (sometimes the SHIFT key must also be pressed) rather than the tedbus practice of typing each word individually. Load — Method by which, a program (with or without data) that is stored on an external storage media (tape or disc) can be trans- ferred into the computer's internal memory. Save — Method by which, a program (with or without data) — stored in the computer's internal memory — can be transferred to an external storage media (tape or disc). Special Character — On the TIMEX Per- sonal Computer, any character other than a number, letter, or graphics character is a special character (Le. $, + , etc ). The T/S 1000 incorporates 21 -special characters within the 40-key keyboard. Thermal Printer — A Printer that utilizes a combination of heat and chemically treated paper to print letters, numbers, graphic characters, or special characters as hard copy. BULK RATE U S.
