You can add two or more strings togethere easily.

a$ = "a"
b$ = " "
c$ = "string"
d$ = a$ + b$ + c$
print d$

ouputs
a string

Deleting parts of a string is more difficult, look up these commands in the help.
LEN, LEFT$, RIGHT$ or MID$

a$ = "a string"
b$ = left$(a$,3)
print b$

outputs
a s

a$ = "a string"
b$ = right$(a$,3)
print b$

outputs
ing

a$ = "a string"
b$ = mid$(a$,3)
b$ = b$ + mid$(a$,5)

outputs
sr
print b$

What about the LEN command as well? Very handy for manipulating stringes. It fetches the number of characters (including BLANK spaces) in a string. You MUST get the number before you begin to manipulate the characters in a string, because if you try to grab the seventh character in a five character string, you will get an error!
