Re: RPG retrieval of MSGID text

Yes, you are correct, Chuck. I mis-typed the example.

Yes, %msgid() would be just exactly what I am looking for.

Looking at the other suggestions, it occurs to me that perhaps I need to first write & read a format with the MSGIDs I want to retrieve, as hidden fields. Or something. Heh heh... more play time. Man I love this platform.

Something like:
wText = MSGID(*LIBL/FILENAME UTL12004)

where UTL12004 is the level 1 text in a specific MSGF.

Any ideas?

Presumably the UTL12004 reference intends to suggest a message
identifier which is seven bytes; i.e. a MsgID of a *MSGF is defined as
having a three byte prefix followed by four hex digits. So either the
MsgID is incorrectly written as eight bytes instead of seven bytes [so
perhaps something like UTL1204 were intended], or the intent was a
decimal specification for an apparent msg UTL2EE4; i.e. whereby 0d12004
= 0x2EE4.

If there was a run-time feature, possibly it would look more like one of:
wText = %MSGID('*LIBL/FILENAME' : 'UTL2EE4') ; // a builtin
MSGID Utl12004 FileName wText ; // e.g. like a READE

I am aware of no such feature. Almost surely requires a procedure to
be coded to define the effect, probably using the Retrieve Message
(QMHRTVM) API [or perhaps a CLLE module using Retrieve Message (RTVMSG)
command]; e.g. perhaps something like one of:
wText = RtvMsg('FILENAME':'UTL2EE4') ;
wText = RtvMsg(FileName:Utl2EE4:'replacementdata':%size(wText)) ;

If one were so inclined, the interface to a Message File could be
coded as a SPECIAL file to allow READ requests, although each of the
OPEN and CLOSE for an I=input-only declaration on the F-spec probably
would be no-ops because the file name might [best] be dynamically
resolved each time to allow the language to change [as implied by the
*LIBL]; and FEOD would have no apparent equivalent function for use with
a *MSGF having its access implemented with a special file.
