Hi all,

I tried to use Search facility but could not find exact answer/solution.


01 WS-A PIC X(5)
01 WS-B PIC 9(5)

MOVE WS-A TO WS-B

I want to keep a test on WS-A, if this has got non numeric field then I want to move zeroes to WS-B. I am doing this to avoid S0C7 if bad data arrives.

Can I use function NUMVAL to prepare my solution?

Or, it would require verifying each CHAR on WS-A?

Many thanks,
zh_lad

More simpler approcah would be to Move WS-A to WS-B and perform IS NUMERIC check for WS-B. If it fails move ZEROS to WS-B else continue with your processing.

Let us know if you are looking for anything more on this.

Why not
Code:
IF  WS-A NUMERIC
    MOVE WS-A TO WS-B
ELSE
    MOVE ZERO TO WS-B
END-IF.
