VTech Precomputer Power Pad Plus CONSTANTS, VARIABLE NAMES, CONTENTS, CURTIS, ALPHABET SOUP, 10 LET A$=“ALPHABET SOUP NO 123”, New, PRINT N, IF N<10 THEN

VARIABLE NAMES	CONTENTS
A	675
B	2.3434
C$	CURTIS
A$	ALPHABET SOUP

Here’s an example of storing a string variable:

10 LET A$=“ALPHABET SOUP NO 123”

You can have a numeric variable called A and a string variable called A$. The $ lets BASIC know how to tell them apart.

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 PO.

CONSTANTS

A constant is something that doesn’t change. The computer stores it in memory just like a variable. However, since a constant doesn’t change it has no variable name. The number 6 is a constant; so is 4.567 or 28967.35. “QUICK BROWN FOX” is a string constant.

You can store constants to a variable. the contents of the variables change.

Type in this program:

That’s usually done to start out a program; later Suppose we want to count to 10.

New		press ENTER
10	N=0	press ENTER
20	N=N+1	press ENTER
30	PRINT N	press ENTER
