I need to check if a S9(3)v9(4) COMP-3 variable is LOW-VALUES or SPACES.

How do I write it in COBOL?

Digitalnirmal,

This comparison is invalid in cobol..Moreover, Can you tell us the reason for doing such comparisons.

Check this link for the comparison rules..

If your intension is to check whether the content of the comp-3 data-item is numeric, you can use the class condition

Hope this helps...

Thanks,

@Jaya
I need to initialize all those COMP-3 fieleds from an IMS DB to ZEROS which are either SPACES or LOW-VALUES.
For this, i need to be able to distinguish them

Would it be safe to say that if they aren't numeric they need to be initialized?

If so, you can code

IF Z NUMERIC
CONTINUE
ELSE
MOVE 0 TO Z.
