"b--" gives the same error. If I change that line to "b=b+1" I get no error. Further, look at GC2.c line 193. The expression "((LCDint == 0) && (i+1 >= digs))" evaluates correctly. If I write "((LCDint == 0) && (i >= (digs-1)))" it doesn't. The term "(i >= (digs-1)))" always eveluates to false. >How-To-Repeat: Hope you get the same when you compile my code. >Fix: As described in "Description", rearranging terms seem to help. I wonder if there's a special problem with a "-" sign right after an integer variable >Release-Note: >Audit-Trail: >Unformatted:
