Greetings Daniel,

I have a quick one for you this time.
I want to strip the first and last character from a string.
What is the most efficient way to do this in BASIC?

Thanks for your help Daniel.

Hi Robert

The easiest way is with the LEFT$, RIGHT$ and LEN functions. Lets call the string A$

Code: Select all
A$="abcdefghijklmnopqrstuvwxyz"
LenA = LEN( A$)
PRINT LenA
'Remove right most character
ShortA$ = LEFT$( A$, LenA-1)
PRINT ShortA$
EvenShorterA$= RIGHT$( ShortA$, LenA-2)
PRINT EvenShorterA$
END


If you run this program it will print
Code: Select all
26
abcdefghijklmnopqrstuvwxy
bcdefghijklmnopqrstuvwxy


Hope this is clear. There is also a MID$ function for breaking strings in pieces.
