How to manage part of a STRING?

[boriel]

Hello,

I am looking at string manipulation, particularly in terms of deleting the last character from a string.

...

It's the "delete last character" routine that I'm having trouble with. the b$(0 TO LEN(b$)-1) isn't doing what I'm expecting, i.e., if the contents of b$ are:

Code:

12345

I want c$ to be:

Code:

1234

and therefore be passed back to the b$ string before returning.

Many thanks for any help or advice.

Regards,

Shaun.

Have you tried with

Code:

b$(0 TO LEN(b$) - 2)

:?:

Since by default ZX Basic strings are 0-based (the standard in BASIC is 1-based, that is, starting from position 1), LEN(b$) - 1 is the position of the last character. So LEN(b$) - 2 is the 2nd to last.

Try this and tell me, please. :roll:
