You can store a string variable like this:
I
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 also
interpreted
as variable PO.
5. 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
.
That's usually done to start out a program;
later the contents of the variables change. Let's see. Suppose we want to count
to 1
o.
Type in this program:
New
10
N=O
20 N=N+1
30 PRINT N
40 IF N<10 THEN 20
50 PRINT "THE ANSWER IS"; N
RUN
25
