This command isn't exactly what I figure it should be. I dont think that negative numbers are valid indexes since they crash the program...Anyway, if i check if an index is valid, and then check if the value of that index is equal to a number if it is valid, the program shouldn't crash because ARRAY INDEX VALID let slip a negative number as being a valid index.

If this command worked correctly, it would save a lot of work since i'm using multi-dimensional arrays.

Any ideas?

Hmm...? Not at all clear what the function is doing. Nothing special about negative index values - try this:

[EDITED]
I did a search in bug reports, turns out you dont give an index as an argument. It is for detecting if the pointer is at the end yet or something...oh well.

They do need a command to check if the index is valid though.

Dimensionalizing always makes indexes go from zero to whatever you want for the max. If you always keep the array within the limits you don't even have to check if it's valid to use it.
