You might want to make life easier for your script / program. I use this on
AIX and NT to provide a text file which is more script friendly.

dsmadmc -id=guess -password=guess -outfile=<name> -commadelimited macro
my.mac

The file my.mac contains
set sqldisplaymode wide < dunno if this is absolutely necessary - takes 5
secs to find out if needs must>
select * from actlog where <and then any criteria, sort etc>

In the output file you get exactly one line per message and each field comma
delimited. Wish there was a way to automatically switch off the headers and
footers adsm insists on sticking in the file - anyone??

Dunno if it helps on OS/390.
