Messages from printer device

[SICAT]

We are developing a emulation of WRKSPLF to include some functionality. We
are able to execute all options except 7=Messages.

How can we show these messages from a specific printer?

Thanks in advance!

Anonymous SICAT,

Hmmm, I've been involved in similar discussions many times before...
I know of no API to do so for any job, and the function is conspicuously
missing from WRKJOB. Specifically, this should be available IMO via a
request:
WRKJOB JOB() OPTION(*MSGW) /* or perhaps OPTION(*DSPMSGW|*MSGWAIT) */

However you are in luck, since the message key and queue name _both_ are
available since V3R1M0 from API QSPRWTRI. Get the writer info from
the QUSRSPLA <I think that's what you are using>, and then use this
other API to get the message queue and message key. Note this only
applies to writers so for a roll-your-own WRKACTJOB... no joy.

After that you are part-way there. Unfortunately there is no API
that I know of to effect the panel "Additional Message Information"
with the reply line ready to accept input for a response given the
message queue and message key. So... you would have to roll-your-own
or perhaps get one from somebody who has already done that. This will
require a combination of RCVMSG and RTVMSG functions <there are APIs>
and SNDRPY after the user enters a reply. My suggestion for an API or
even the noted enhancement for WRKJOB handles this. I hope this helps.

BTW, please don't anyone hesitate to correct me if I am wrong on any
account... I have not kept a close watch on this stuff <ie. beyond V3R1>
