    CHAPTER 6 BASIC INTRODUCTION ARE COMPUTERS IMPORTANT? Computers are all around us. Like cars, phones and TVs, computers help us make our lives easier. Millions of computers are used everyday. Doctors use computers to treat patients. Police use computers to track criminals. Stores use computers to add up prices quickly and so on.
  • Page 31 To do this requires us to learn how to talk to our computer. This chapter will help you to get started. All you need is your PRECOMPUTER PRESTIGE learning unit and some time. WHAT IS THIS CHAPTER FOR? This chapter is a step-by-step guide for understanding programs and learning to use the computer language called BASIC.

  • Page 32: The Keyboard

    When using the INPUT command, PRECOMPUTER PRESTIGE will ask you to supply it with some data from the keyboard. PRECOMPUTER PRESTIGE tells you it needs input with a prompt. The prompt is the "?" symbol and it appears on the display indicating that the computer is waiting for you to type something.

  • Page 33: The Display

    GETTING STARTED This activity lets you type in your own programs and run them. Follow these simple steps: 1. Turn on the PRECOMPUTER PRESTIGE unit. 2. Click the Business Basic icon from the main menu.
  • Page 34 Each time you press Enter, the next lines are displayed. You can stop this by pressing the Shift and Break keys. If you enter the command with a line number after the word, i.e., LIST 50, PRECOMPUTER PRESTIGE will list the statement at line 50.
  • Page 35 Now type RUN and press Enter. What happens? You get the strange message, "? SYNTAX ERROR IN 10" in the display. That means you made a mistake in BASIC grammar and this is the PRECOMPUTER PRESTIGE unit’s way of telling you this. You need to EDIT the line or re-type it, changing "PRONG"...
  • Page 36 You can use PRECOMPUTER PRESTIGE as a calculator in arithmetic statements like the one above by not using a line number. Just type: PRINT 12-4+7 and press Enter The answer will appear on the display. Another short cut is that you could use the "?" symbol to stand for the word "PRINT".
  • Page 37 Type: 10 PRINT 2^10 When you use all the operations together, it can get a bit complicated. After a winning baseball game, your 7-person team is awarded 3 cans of pop for the game plus another 11 cans because you finished first in the league too. How many cans does each player get? Type this: 10 PRINT 3+11/7...
  • Page 38 NUMERIC VARIABLES You have seen how you can use BASIC to print numbers and messages. You can also give values to a BASIC program yourself. The computer uses a letter to stand for a value. This is called a variable. For example LET D = 609. This statement puts the value 609 into a box in memory called "D".
  • Page 39 Now let’s finish this by typing: 50 PRINT "FIRST NUMBER"; A 60 PRINT "SECOND NUMBER"; B 70 PRINT "THE SUM IS"; C You will see the following on the display: FIRST NUMBER 8 SECOND NUMBER 15 THE SUM IS 23 (Don’t forget to press Enter after you have seen each line to get the next one displayed.) Let’s take a look at the print statements on lines 50 through 70.
  • Page 40 Let’s try. Type: 10 PRINT 3000000*3000000 The answer on the display is 9E+12. This is the computer’s way of showing extremely large numbers. A number with the letter E and a number to the right of the decimal point is called scientific or exponential notation. You find the decimal point and move the number of places specified after the "E"...
  • Page 41 NOTE: For both numeric and string variables, only the first 2 characters of the variable names are valid. Also, they cannot resemble the name of any command. Examples: TOTAL is interpreted as the TO command and POTATO is interpreted as variable CONSTANTS A constant is something that doesn’t change.
  • Page 42 The program in the above example contains a programming construction called a loop. A loop is one or more BASIC statements, usually called a set, that can be executed as many times as you want. The statement in line 40 contains an IF statement. It is called a conditional statement and will be discussed in detail under the topic called Making Decisions.
  • Page 43 Try this: 10 INPUT "GIVE ME A NUMBER"; N1 20 INPUT "AND ANOTHER"; N2 30 PRINT "I WILL ADD THEM" 40 C=N1+N2 50 PRINT "THE ANSWER IS"; C Type RUN and press Enter to see what happens. MAKING DECISIONS The IF statement tells the computer that it has to make a decision. It does this by comparing two numbers, arithmetic expressions or string variables.
  • Page 44 A condition is either TRUE or FALSE. The IF statement has a condition. The computer evaluates the condition and decides that if a condition is TRUE it will do something for the TRUE condition. Take the following: IF A > 90 THEN PRINT "YOU ARE SMART" The A >...
  • Page 45 This program uses the INPUT statement to get values for numeric variables and prints a computed result. It then prompts for a string variable and makes the decision to begin again if the value typed in is a Y. Here’s another one. Type: 10 INPUT "GIVE ME A NUMBER";A 20 INPUT "AND ANOTHER";B...
  • Page 46 140 PRINT "YOU MADE A MISTAKE" 150 PRINT "TRY AGAIN" 160 GOTO 30 200 PRINT "THE ANSWER IS";C 300 END This is a long program but it has a lot of new things in it that are worthwhile to know about.
  • Page 47 You can modify the program to get out of a loop by using an IF statement to control the loop like the program that calculates the area of a rectangle. Another way to create a loop is through the use of the FOR and NEXT statements. These statements surround the instructions that you want to repeat.
  • Page 48 Are they the same? We can also count by 2’s. Let’s bring back the previous program and change line 10. The entire program looks like this: 10 FOR N=1 TO 10 STEP 2 20 PRINT "N IS";N 30 NEXT N The STEP 2 part changes the meaning hidden in the NEXT N statement to be N = N + 2 or any other number that gets put in the STEP part.
  • Page 49 MORE ABOUT GROUPS - GOSUB ... RETURN How much is 10 degrees Celsius in Fahrenheit? What is 100 degrees Fahrenheit in Celsius? Here’s a program that gives you the answers. It uses the GOSUB and RETURN statements to create a group of instructions that can be executed from various parts of the program. Remember when you use a GOSUB, the program branches to the line number that you specify in the statements that will be executed sequentially until a RETURN statement is encountered.
  • Page 50 510 PRINT "THE FAHRENHEIT TEMP IS";F 520 RETURN 600 C=(F-32)*5/9 610 PRINT "THE CELSIUS TEMP IS";C 630 RETURN REFERENCE SECTION The REFERENCE SECTION contains a brief explanation of all the commands and statements you will use in this chapter. Refer to this when you need help. CLEAR The CLEAR statement is used to assign more memory space for the string variables.
  • Page 51 Line # DIM array-name (array-size). The DIM command reserves space for one dimensional numeric or string arrays. The array- name may be up to 6 characters long but only the first 2 characters are valid. For a string array the last character must be a $. The array can contain up to 100 elements (0-99).
  • Page 52 Line # END The END statement is used as the last command in a program. It stops the program. Examples: 160 END 999 END PSET This command is used for drawing a specified point on the screen. PSET X, Y (X, Y) is a coordinate of the specified point to be shown.
  • Page 53 Example: 10 CLS 20 FOR X= 50 TO 100 30 PSET X, 8 40 FOR DELAY= 1 TO 70 50 NEXT DELAY 60 PRESET X, 8 70 NEXT X 80 END VOICE This is a command to generate voice. VOICE(X) X is the voice number A LIST OF AVAILABLE VOICE Voice Num(X)
  • Page 54 Z(Zed) Z(Zee) FOR ... TO ... STEP ... NEXT Line# FOR variable = initial value TO final value STEP step size (optional) Line# Line# Line# Line# NEXT variable...
  • Page 55 The FOR ... NEXT statement repeats a task a set number of times without having to rewrite it. All statements between the FOR and NEXT command are repeated based on the initial value, the final value and the step size. If the STEP portion of the command is not used, it is assumed to be 1.
  • Page 56 A LIST OF NUMERIC FUNCTIONS Function What it does ABS (X) Returns the absolute (postive) value of X SGN (X) Returns the sign of the argument X negative returns -1 X postive returns + 1 X zero returns 0 SQR (X) Returns the square root of X.
  • Page 57 SGN (X) This function will give the value of +1 if X is positive, 0 if X is zero, and -1 if X is negative. So SGN(4.3)=1; SGN(0)=0; SGN(-276)=-1 Example: press Enter PRINT SGN (A); SGN (A-A) press Enter INT (X) This converts arguments which are not whole into the largest whole number below the argument.
  • Page 58 This function computes the length of the string argument, which must be in brackets. So if you type PRINT LEN ("JOHN") the computer will return the result 4. This is telling you that there are 4 characters in the string "JOHN". Blank spaces have the value of characters.
  • Page 59 Example: 10 A$="33" 20 B$="20" 30 C=VAL(A$+B$) 40 D= VAL (A$) + VAL (B$) 50 PRINT C;D 3320 53 GRAPHICS FUNCTION PGET Returns the color attribute of a specified pixel. PGET(X, Y) = n Returns the current coordinates (X,Y) turns the pixel status ON the current coordinates (X,Y) turns the pixel status OFF SUBSTRINGS It is also possible to get substrings of strings.
  • Page 60 Example: 10 A$="ABCDE" 20 B$=LEFT$ (A$+"FGH",6) 30 PRINT B$ ABCDEF RIGHT$ (A$,N) This will return a substring but starting from the Nth character from the end and running to the last one - the right-most character in the string A$. Example: 10 A$="WHY"...
  • Page 61 MID$ (A$,M,N) This function returns a substring of the string A$ starting from the Mth character with a length of N characters. Example: 10 A$="ABCDEFGH" 20 B$=MID$(A$,2,3) 30 PRINT B$ ASC(A$) The ASC statement will return the ASCII code (in decimal) for the FIRST character of the specified string.
  • Page 62 RETURN statement is used to send the computer back to the line immediately after the GOSUB. These statements are used to process a series of commands that are frequently used. Example: 30 GOSUB 120 other program lines 120 PRINT "WELCOME TO THE" 130 PRINT "PRECOMPUTER PRESTIGE" 140 RETURN...
  • Page 63 GOTO Line # GOTO line number The GOTO statement is used to change the normal flow of the program(which is from the lowest statement number to the highest). A GOTO command transfers control to the specified line. Examples: 10 GOTO 130 200 GOTO 65 IF...THEN...ELSE In general terms, the IF...THEN...
  • Page 64 Example: 30 IF X >25 THEN 60 If the condition X>25 is true, the computer is told to jump to line 60 (Note: the GOTO is optional after THEN). If the condition is not true, that is, if X is not greater than 25, then the computer simply carries on with the normal line number order in the program.
  • Page 65 Example: 40 IF P=6 THEN PRINT "TRUE" ELSE PRINT "FALSE" In this example, if P=6 the computer will print TRUE. Any other value will produce a FALSE. In either case the computer will carry onto the next line. It is possible for more than one statement to follow the THEN or ELSE command. A colon separates the statements.
  • Page 66 TRUTH TABLE FOR "NOT" FUNCTION NOT A TRUTH TABLE FOR "AND" FUNCTION A AND B TRUTH TABLE TABLE FOR "OR" FUNCTION A OR B Note that T = TRUE and F = FALSE. Example: 10 INPUT A,B,C 20 IF A=B AND B=C THEN PRINT "A=B=C" 30 IF (NOT A=B) OR (NOT B=C) THEN 50...
  • Page 67 40 END 50 PRINT "A=B=C IS FALSE" 60 END ? 10 ?? 5 ?? 7 A=B=C IS FALSE Moreover AND, OR, and NOT can be used to manipulate numerical values. These operations are based on binary numbers with 1 and 0 representing TRUE and FALSE respectively. For example: i) NOT 1=-2 [1=binary 00000001 and -2=binary 11111110, so it just changes the 1 to 0 and 0 to 1.
  • Page 68 Line # LET variable = variable expression The variable expression is calculated and the result is stored under the variable. The word LET is optional. Examples: 40 LET SUM=A+B+C 25 LET AMOUNT=PRICE-DISCOUNT LIST LIST (optional line number) LIST is used to display the active program. If the optional line number is omitted, the program will be displayed from the first line onward.
  • Page 69 Example: 80 PRINT NAME$; "IS COMING" 230 PRINT "SUM="; A+B+C READ AND DATA When it is necessary to enter a lot of information or data into the computer, using the INPUT statement can be very time consuming. To help out use the READ and DATA commands.
  • Page 70 Example: 10 DATA 1,3,8,9 20 READ A,B,D 30 RESTORE 40 READ X,Y 50 PRINT A;B;D 60 PRINT X;Y 70 END 1 3 8 The RESTORE command makes subsequent READ statements get their values from the start of the first DATA statement. Now see if you can work out what is happening here.
  • Page 71 80 NEXT 90 A=S/8 100 PRINT A 9.52813 Line # REM text REM is used to add comments in your program which are ignored when the program is RUN. Example: 10 REM**GUESSING GAME** 20 REM TEST OF SORTING RUN tells the computer to begin to perform your program beginning with the lowest statement number.
