string slicing using len()

[programandala.net]

Notice also that FOR upper limit is evaluated ON EACH iteration (like C). So if len(a$) changes, the loop will shorten. So better use a temporary var l to store initial LEN(a$).

I learned it while debugging. It's an important difference with Sincllar Basic.

Arrays subscripts starts from 0 to N-1 (like in C). But this behavior can be changed using --sinclair or --array-base switch.

I forgot it! Thanks. One of my tests used "-2" intead of "-1" because of that. Anyway, the problem arises when trying to remove the last char of the string. Then "-2" cannot be used. I tried the following expression:

Code:

let text=text( to len(text)-2+(len(text)=1))

It doesn't work because

Code:

(len(text)=1)

doesn't return "1" when true, as I expected (Sinclair Basic does).

I opened a new thread about this different issue.
