Ok I'm still not sure how to use this am I supose to; after using dim x(100), do an undim x(0) or an undim x(100) and also what if im using multidimension?

I have been programming with DarkBASIC for a little more than 4 years, and that is a very good question, because I also do not know...

But I undim a dimension the same way I dim a dimension:

I've used this syntax in DBC and it worked ok for me:

dim stuff(100,3)
undim stuff(100,3)


Technically, WindowsKiller is right in that you shouldn't need to specify the size of the array.

Hmm so either way works right? I've crashed a few times while testing my codes over and over, is the a result of not enough memory cause I didn't clear them out properly? It's why I wanted to know the correct usage of undim.

Why would you want to delete an array? They aren't like memblocks; they don't take up a lot of space. The only reason I would undim something is if I am desperate to move up a framerate, but I don't think it affects that at all.

Its not always to free memory, maybe he needs to repopulate an array with an unknown size of elements? I had to for a file scan program.
