Always, always use integer for any kind of loop counter or any other
counter. The speed difference is huge. Decimal arithmetic is extremely
slow compared to integer.

Did the program crash, or go into an endless loop? I would have
expected an endless loop, but I am wrong so often I decided to ask.

Hi everyone,

A coworker got caught out by the For EndFor loop.

D wI S 3 0

For wI = 1 to %elem(arrayWith999Elements)

etc.
EndFor;

I said it was normal at the end that wI should be incremented to 1000,
thus making the program crash.

I wondered what the normal way would be to avoid this. I always use 5I
0 for my array index.
The coworker changed the DIM setting to 998!
