Re: Data area in a service program (was Re: Pointer Question)

Hi Phil,

You don't need the 'u' on the 'uds'. Get rid of it and all should work fine.

The 'u' means that there is an automatic IN of the data area when the program
loads, and an automatic OUT when the program ends. But this is controlled by the
RPG cycle, and with NOMAIN specified.........

If you do need to update the data area, then you need to specify *LOCK in factor
1 of the IN operation.
