mainframe - Loop until data set is not in use with JCL -


i working in mainframe , need wait dataset released execute automatically job. know simple way loop until dataset not in use in jcl? looking on web , found solutions rexx seemed complicated such simple thing need. have never used rexx.

regards!

p.d. also, data set not exist.

edit: need becouse run xcom job transfer file of system mainframe dataset. problem when job finish, maybe file still beign transfered, , wait transfer completed before start next job. maybe editing sentence of next job associated dataset.

the easy way ensure file transfer package allocates dataset old disposition, create system level enqueue on dataset , prevent job running until enqueue released.

many file transfer packages offer sort of 'file complete' exit can trigger job once dataset transmission complete.

but can't loop in jcl. can in rexx, has host of issues have deal with, not @ simple.
