A Slow Fast Loop... Or Bad Coding?

[variant]

Okay, here is the problem I am having with my fast loops, type or paste a large amount of text into the top text area, then click "Go!". You will notice that the application will sort of freeze, and after a long while the output text will finally be visible. I do not know what I did wrong, I coded it efficiently as possible, at least as far as I know. Related to this post.

Yes, making constant changes to an edit box during a fast loop is slow. What you should do is make a global string variable, edit/append data to the global string variable in the fast loop, then copy it to the edit box after the loop.

Yep, checked out the code and problem is you're using an immutable string type. Each it appends a string by doing:


"set text of edit box = string + %"


it does this not by altering the existing string, but rather by creating an entirely new string and setting its value to this result. So each append action constructs a new string, of length of the current result. So for the entire thing, you'll end up using (# of loops) * (length of output / 2) size of string objects. I think ryan is correct that global strings are mutable and thus you could edit them with little slowdown, but I personally use the binary data object

The percent (%) sign is a delimiter, I'm not really sure how that would work, but I'll try it, thanks.
