It’s Operator Precedence that gives the zero result, just as has been explained. The position of the minus sign is nothing to do with it. Abutting the sign against the parenthesis does NOT turn it into a ‘unary’ operator – try changing your code and see.

How do you get this:

“XXAVAL= 30 + (60-) + 30 making XXAVAL = zero.”

From this:

XXAVAL= LTSTHQ-(LTCUSQ+LTPICQ+XPQTY)+OLOLQT

???

Where did your new plus sign come from? It just appeared from nowhere! If the code actually WAS

XXAVAL= LTSTHQ+ -(LTCUSQ+LTPICQ+XPQTY)+OLOLQT

then you would be correct. But that’s not what you have got. So, please understand what advice you are being given, because if you continue to think that evaluation depends on operator spacing you will end up making some serious mistakes.
