Hi,
I used SORT step in my job. I defined the SORTWK files like,
//SORTWK01 DD UNIT=SYSDA,SPACE=(CYL,30)
//SORTWK02 DD UNIT=SYSDA,SPACE=(CYL,30)
I didn't use RLSE in SPACE. Will it occupy more DASD storage when it run?
Here, what is the use of RLSE? If I ll declare like SPACE=(CYL,30,RLSE) then what is the diff it will make?
Please correct me If Im wrong, RLSE is used to release the reaminig space in flat files. |

Check the sysout from the run. I think that you will find that because you have not coded a DISP parameter the temp files will be deleted at end of step, the same time as the RLSE parameter would be actioned, so in effect it would not use extra space.
However, as the system setup may vary, you need to check your own sysout to see what happens. |

RLSE is most useful for files that will remain beyond end-of-job. This saves space by releasing unused tracks/cyls.
Temp files delete at EOJ so RLSE is no big deal. |
