Re: MAPVAL issues

Ok, so in the DDS he declares this field for INPUT only, meaning that this
field will be in the INPUT data structure, but not OUTPUT. How does RPG
map dcl-ds dsprec likerec(display: *all) when input and output formats are
different?

I still think all he needs to do is define the field for BOTH input and
output...

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?
