Answer / stu
DISP=(xxx,yyy,zzz) where
xxx=how the file is treated by your program. New=create,
SHR=exists, share with other jobs, OLD=exists, lock it
while the program uses it, MOD=it may exist, but if it
doesn't, create it.
yyy=what to do with the file if the jobstep completes
successfully. CATLG=catalogue a new file, KEEP=keep the
file with any changes made by the program, DELETE=delete it.
zzz=what to do with the program if the jobstep does not
complete successfully. CATLG=catalogue a new file,
KEEP=keep the file with any changes made by the program,
DELETE=delete it.
Example:
DISP=(NEW,CATLG,DELETE) will create a new file, catalgue and
keep it if the jobstep completes OK; otherwise delete it
without cataloging.

Answer / guest
The MOD will cause the dataset to be created (if it does not
exist), and then the two DELETEs will cause the dataset to
be deleted whether the step abends or not. This disposition
is used to clear out a dataset at the beginning of a job.
