CHAPTER 5:

The PRECOMPUTER POWER PAD PLUS offers you one of the first and most important applications found in computers: word processing. With this word processor, you will be able to create, edit, save and print documents you have created. The unit can hold approximately 3500 characters or 500-600 words before data has to be saved or printed.
The bottom line represents the status of the text on the screen. L=1 L stands for a line of text. The number (i.e. 1) represents the first line of text. L=2 would mean the user is editing the second line of text. A line of text refers to one line (60 characters) on an 8 1/2 X 11 sheet of paper - not one line on the LCD viewing screen. PLEASE NOTE THAT 60 CHARACTERS WILL TAKE UP 3 LINES ON THE LCD VIEWING SCREEN BUT TRANSLATE TO ONE LINE OF TEXT ON AN 8 1/2 X 11 SHEET OF PAPER WHEN PRINTED (SEE PRINT SECTION). This feature allows the user to effectively print documents using a standard 8 1/2 X 11 format. 20
J=L means the current line is justified left. NB means the current word is not bolded. B means the current word is bolded.
CH means which character the cursor is on in a particular line. PLEASE NOTE THAT THE VT-25 THERMAL PRINTER PRINTS 25 CHARACTERS PER LINE ON A STANDARD ROLL OF THERMAL PAPER. YOUR PREPARED TEXT WILL AUTOMATICALLY BE ADJUSTED TO FIT THIS FORMAT WHEN YOU SELECT THE VT25 THERMAL PRINTER IN PRINTER SETUP. WHILE THE FORMATTING WILL NOT CHANGE ON THE LCD SCREEN, THE TEXT WILL PRINT CORRECTLY TO FIT THE VT25 FORMAT. The Word Processor has a menu with many functions. You may view the Word Processor menu by pressing the Help key. The Word Processor menu will appear with the following options: File, Edit, Format, Tools, Print, Help and Exit.

FILE OPTIONS

Under the File Options menu, you may select four different functions: New, Load, Save and Delete. To enter the File Options menu, press the Help key and select File Options.
New is the command to create a new file. Every time you enter the Word Processor activity, you will see the same document you worked on the last time you were in Word Processor. To create a file, select New from the FILE options and it will ask if you want to create a new document. If you select Yes, it will ask if you want to overwrite the current document. If you select Yes, the document will be deleted, allowing you to create a new one. Selecting No will return you to the existing document. If you want to save your document in order to create a new one, you must have a RAM cartridge. This cartridge allows you to save multiple documents and is sold separately.

TOOLS OPTIONS

This command instructs PRECOMPUTER POWER PAD PLUS to begin executing each BASIC statement with a line number that was typed into memory. The computer will start with the lowest line number and proceed up to the highest numbered statement.
Use the EDIT command when you want to change a statement that has been typed into memory without re-typing the entire line. Type EDIT and the line number and press the ENTER key. The statement will appear on the display. Use the LEFT-ARROW and RIGHTARROW keys to move the cursor. Use the DEL key to remove an unwanted character, or type in a new character. You can type in line-numbered BASIC statements in any order. The PRECOMPUTER POWER PAD PLUS will sort them out for you and LIST them or RUN starting with the lowest numbered statement to the highest numbered statement. It is a good idea to number your lines in increments of 10 (10, 20, 30.) or 100 (100, 200, 300.). This way you will have room to add more statements if you decide to change your program in the future. You line line the can insert an entirely new line in a program between two existing ones by using a number that doesnt exist. To delete an existing line-numbered statement, type the number and press the ENTER key. You can also change an existing line by re-typing entire line.
When you want to type in a program, type in the line number before the statement. With the AUTO function, the line number will generate automatically. e.g. AUTO AUTO 100 AUTO 100, 5 generate the line no. increments of 10 generate the line no. increments of 10 generate the line no. increments of 5 i.e. To end the AUTO mode, press ENTER without input or press the SHIFT key and the BREAK key at the same time. starting from 10 with starting from 100 with starting from 100 with
This command causes the program to resume executing after encountering the BASIC command called STOP. The program will be carried on with the next statement after STOP. Type CONT to resume the program after you press the SHIFT and BREAK keys.

BASIC COMPUTER TUTORIAL

EXAMPLE OF A BASIC PROGRAM
You and Teresa went to the local video store to rent some movies. Teresa brought back 12 but 4 were too scary for you so you returned them. On that trip you came home with 7 new movies. How many are you going to watch this afternoon? You could work this out yourself, but here is a BASIC program that can do the arithmetic for you. Type in:

PRINT 12-4+7 END

press ENTER press ENTER
Now type RUN and press ENTER. What happens? The answer, 15, appears on the screen. In BASIC, you write a series of line-numbered statements that tell the PRECOMPUTER POWER PAD PLUS what to do. The first statement, numbered 10, tells the computer to work out the sum of three numbers and then PRINT the answer on the screen. The next statement, number 20, tells the computer that this is the end of the program and that it can stop RUNNING. However, the last statement is not necessary in this program because you only want to print out the sum of 3 numbers, therefore, it could be removed. Remove that last line by typing 20 and press ENTER. Now type RUN and press ENTER. What happens? You get the same results. Suppose you typed:

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. How many cans does each player get?

Type this:

PRINT 3+11/7
Is it really evaluated from left to right? Yes, but was it the answer you were expecting? If the answer came out to 4.57143, the computer first divided 11 by 7 getting 1.57143 and then it added 3 to the result giving 4.57143. You probably were expecting the answer to be 2 because 3+11 is 14, then divided by 7 is 2. You can see that expressions are not simply evaluated from left to right. It is necessary to have an exact set of rules to follow. Here they are:
Functions ( ) ^ * / + things in parentheses raising to a power multiplication and division addition and subtraction
Order in which they are performed (1st) (2nd) (3rd) (4th)
The computer will always look at an expression in parentheses first and follows those commands. It could be an expression or more sets of brackets. Among the expression, raising to a power is calculated first, followed by multiplication and division from left to right, followed by addition and subtraction from left to right. If youre not sure how the computer will evaluate the expression, simply put brackets around the expression you want computed first. Remember the brackets must always be in pairs, one right bracket for each left one. If you dont use both brackets, you will receive a ? SYNTAX ERROR message.

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 memory box called D. Try this. Type:

LET A=8

The computer creates a box in memory and calls it A. It puts the number 8 in this box. Now type:

LET B=10

The computer creates a box called B and places 10 into it. Type:

30 LET B=15

Since there is a box called B already with a value of 10 in it, it doesnt make another box called B with a value of 15 in it. The number 10 is just replaced with the number 15. Now type:

LET C=A+B

This statement is a bit more complicated. Heres how it works. First, the computer searches for a memory box called B and finds the number 15. The + sign tells the computer to add the numbers found in A and B together. It computes this and the answer is 23. Now, where is the answer placed? The = tells the computer to store the answer in a memory box called C. The computer searches for a box called C. It doesnt find one so it creates one in memory and then puts the answer there. Of course, if there was a memory variable called C that had a number in it from a previous operation, the old number would be replaced by the new one in this statement. Now lets finish this by typing:

Also see STOP

This command causes the program to resume executing after encountering the BASIC command called STOP. The program will carry on with the next statement after STOP. You can type CONT to resume the program after you hit the SHIFT and BREAK keys.
Line # DIM array-name (array-size). The DIM command reserves space for one dimensional numeric or string arrays. The arrayname 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). Example:

DIM FRIEND$(50)

DIM PRICE(19)
Use the EDIT command when you want to change a statement that has been typed into memory without re-typing the entire line. Just type EDIT and the line number and press the ENTER key. The statement will appear on the display. Use the LEFT-ARROW and RIGHT-ARROW keys to move the cursor. Use the DEL key to remove an unwanted character, or simply type in new characters. Example:

INPUT B

EDIT INPUT B_
Then use Left-Arrow key to move the cursor back underB.

Then type in C.

INPUT C_
You can type in line-numbered BASIC statements in any order. PRECOMPUTER POWER PAD PLUS will sort them out for you and LIST them or RUN them starting with the lowest numbered one. It is a good idea to number your lines in increments of 10 (10, 20, 30.) or 100 (100, 200, 300.). This way you have room to add more statements if you decide to change your program in the future. You can insert an entirely new line in a program by using a line number that doesnt exist between two existing ones. You can delete an existing line-numbered statement by merely typing the line number and pressing the ENTER key. Of course, you can change an existing line by merely re-typing the entire line.
Line # END The END statement is used as the last command in a program. Examples: It stops the program.

160 END 999 END

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.
X represents a value of a horizontal position. Y represents a value of a vertical position.

Example:

The result:

CLS PSET 100, 8

a screen pixel at coordinate (100, 8) will be turned on.

PRESET

This command turns off a specified point on the screen. PRESET X, Y (X, Y) is the coordinate of the specified point to be cleared. X Y represents a value of a horizontal position. represents a value of a vertical position.
CLS FOR X= 50 TO 100 PSET X, 8 FOR DELAY= 1 TO 70 NEXT DELAY PRESET X, 8 NEXT X END
This is a command to generate a sound note. SOUND consists of two functions: frequency and duration frequency The frequency of the sound in hertz; a value in the range 0 < frequency parameter < 256 duration The number of the system clock ticks so the sound lasts; a value in the range 0 < duration parameter < 256
