STRING FUNCTIONS

We can also use functions to act on strings. Take a look at the following:
LEN
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".
characters. Thus if you put in spaces "J O H N", it comes out as 7 characters.
STR$
The STR$ function changes a number argument into a string. Take a look at the following
example and see how it works.
Example:
A$=STR$(73)
This is the same as saying A$="73".
Here is a sample program.
Type the next example:
10 A$=STR$(7*3)
20 B$=A$+"BIG"
30 PRINT B$
RUN
21BIG
press ENTER
Blank spaces have the value of
