Re: Display file DDS using ERRSFL and DSPATR(PR)

Hi Gerald -

I have a DDS display file, that uses ERRSFL. The dspf contains only one
format. Many fields in the format use ERRMSGID to display error messages,
with each message being indicator conditioned.

Recently a requirement was requested to add field protection to an existing
field on the record. A line of code - DSPATR(PR) conditioned on *IN68 -  was
added.

The problem is that even though *IN68 is on, the field protection doesn't go
into effect and the field remains input capable.

There are special restrictions when using ERRMSG or ERRMSGID. They are documented in the DDS reference manual ...

http://publib.boulder.ibm.com/iseries/v5r2/ic2924/index.htm?info/rzakc/rzakcmst76.htm

Specifically ...

    * When an ERRMSG or ERRMSGID keyword is in effect, no processing
      other than the processing for these keywords is performed for
      the record. If neither keyword is in effect, the record is
      processed in the normal manner.

You need to turn on *IN68 (leaving the indicator for the ERRMSGID off), WRITE the record format, then turn on the indicator for the ERRMSGID and EXFMT the record format.
