Stephane,
Put a breakpoint on VARTYPE(i)="N" and check lcCommand right after it has been changed to "C".

>>LOCAL i

>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?
