Re: Saving multiple source files to a single savf

ODOBAT has only whether it is PF or PF38 - the SRC part comes from the file 
description. Makes a weird kind of sense if I think hard enough!!

There is a field ODOBAT in the output file that identifies that record 
as a source file. When your program reads the file, check that field 
and skip the save if it's not a source file. You will have to read 
every record in the file and save only the source files.

I won't b/able to dspobjd to a file and then savobj all the entries though 

since some are not prefixed by Q. 

Thanks for your help

I did mention doing the DSPOBJD to an output file, reading that, searching 
for ODOBAT = the designator for source physical file. Then construct your 
SAVOBJ command from that. 
However, it would be a disservice of me to not suggest a different 
alternative. The problem with using IBM output files is that they can, 
and do, often change with new releases of OS. Often I will use the Object 
APIs instead. After all, who wants a "record format level check" when 
you're already wrestling with other surprises resulting from an OS 
upgrade? 

Granted, one way to get around most record format level checks is to 
eschew the use of any F spec in RPG to open that file and to use imbedded 
SQL instead. Being careful NOT to use "select all from ...". Because 
selecting all from a file that has been updated to hold Y number of fields 
into an externally defined data structure that only had X fields at the 
last compile is a fatal error. Once upon a time, several versions back, 
it wasn't. You just hoped that they kept new fields at the end.
