Re: MAPVAL issues

If it's input only, there's no reason for the 5250 code to change it on a
read. In other words, the MAPVAL code would only come into play on the
output of the screen not the read.

You need to make sure that the subfield is initialized properly.

The fields start out empty, I am not loading anything into them. That

It doesn't appear that you are initializing the DS...so what are you
loading to it?

Are you using OVRDTA / PUTOVR keywords by chance...though I wouldn't expect
those to matter for an input only field...you said in another post you
started with a Both.

I'm wondering if the problem is in the i/o to the DS.

I'd try doing an exfmt using I & O -specs jsut to see if it works there.

Does anyone use the MAPVAL keyword? I am having the following issue,


My date field is defined like so:
A RPTDT L I 5 29DATFMT(*USA)
A MAPVAL(('01/01/0001' *BLANK))

I am reading into a data structure defined like this:
dcl-ds dsprec likerec(display: *all);

But when I read the record (using EXFMT), a blank keyed on the screen is
input as a blank which causes invalid format error when the field is

used.

What am I doing wrong?
