Re: Writing a CL to save changed objects from *ALLUSR libs

Jean Claude -

After the SAVCHGOBJ command, use RCVMSG (in a loop) to receive messages and
check to see if the CPC3708  message is issued.  If so, delete the save
file, since it is empty...

Subject: Writing a CL to save changed objects from *ALLUSR libs


Hi all,

I would like to make a SAVCHGOBJ on *ALLUSR libraries to disk, not to tape.
Goal is to send it to a backup system. To save into files, I have to create
a file per library because SAVCHGOBJ *ALLUSR doesn't work when saving on
file. So I wrote a CL that first lists *ALLUSR libraries, then creates a
file with the name of the library to save and then saves. Here it is :
PGM
             DCLF       FILE(SAVES/LSTLIB)

             DSPOBJD    OBJ(*ALLUSR) OBJTYPE(*LIB) OUTPUT(*OUTFILE) +
                          OUTFILE(SAVES/LSTLIB)
LECTURE:     RCVF
             MONMSG     MSGID(CPF0864) EXEC(GOTO CMDLBL(FIN))
             IF         COND(%SST(&ODOBNM 1 3) *EQ 'SAV') THEN(GOTO +
                          CMDLBL(LECTURE))
             CRTSAVF    FILE(SAVES/&ODOBNM)
             MONMSG     MSGID(CPF7302)
             SAVCHGOBJ  OBJ(*ALL) LIB(&ODOBNM) DEV(*SAVF) +
                          SAVF(SAVES/&ODOBNM) CLEAR(*ALL) SAVACT(*LIB)
             MONMSG     MSGID(CPF0001 CPF3702)
             GOTO CMDLBL(LECTURE)
FIN:
ENDPGM

It works fine, but I would like to know if something has been saved into
file to delete it if not. I see 2 ways :
- When SAVCHGOBJ saves some objects, completion message CPC3723 is sent, and
when nothing is saved, message CPC3708 is sent. But basic MONMSG doesn't
work.
- DLTF save file before creating it and test if file is empty after
SAVCHGOBJ. But how ? It must be so simple, but I have no idea.

Some idea ?

Thanks.
Best Regards.
