It's already declared as a LOCAL variable before the loop. I just didn't include it in the example.

It's really being converted because, for example, at the end of the loop, it's suppose to contain the numeric value 248000 and it's set to '248000' (char value) instead...

Any other ideas?

I can easily correct the error by re-converting the char value to a numerical value before the end of the FOR loop but I really want to understand the meaning and cause of the error.
