No, because this particular program doesn't open any other files. But 
retrieving an object description on something known to be in the 
environment library is (and that's exactly what happens in another 
program in the same application).
I think, since I'm already getting a JOBI0100 for another purpose, I may 
as well bump it up to a JOBI0400, since both have the fields I'm already 
getting. I was merely hoping that there was someplace I was overlooking, 
where I already had that information.
And Chuck, if somebody is really enough of a doofus to go into a server 
job and change the PRTTXT, then they deserve whatever malfunction they 
might cause. After all, nothing is ever completely foolproof, because 
complete fools are so ingenious.
  True.  There is no cure for stupid. :-)
  However what I alluded to was the calling of any program which 
might have the undesirable effect of changing the print text value 
[i.e. with CHGJOB JOB(*)], not for some user invoking the CHGJOB 
JOB(named).  For instance, a "CALL CJD" coded in the application 
might not currently issue a CHGJOB JOB(*) PRTTXT('CJD REPORT'), but 
what controls are in place within the application development 
environment to ensure that is not done in a future revision?  Is 
program CJD even part of the source controlled code, or could it be 
vendor code changing the PRTTXT for their own purpose; whammy bug, 
then beg them to fix it, or remove their /enhancement/ which impacts 
the internal app.  Even within source control, one can not easily 
intuit a need to avoid using CHGJOB to modify various job attributes 
appropriate for declaring some assumptions, but the same programmer 
is unlikely to overwrite data in variables which are declared and 
documented only to the application as the "application name" & 
"port" or whatever.  FWiW I really dislike such dual-use in 
programming if\when that is easily avoidable; i.e. is "print text" 
value the printer text, or does the "print text" define the 
application name & port?
  If the information from JOBI0100 is limited to a few specific 
attributes, one of the "key APIs" that I noted [for their ability to 
retrieve just the attributes of interest and thus limited return 
data size] may be preferable to the QUSRJOBI [with its "formats" of 
pre-defined control blocks of sizable returned information].
