Then from that message I would suggest that the candidate volumes prevent the freeing of space. So how is your DataClass set up for this file?
For a multivolume data set that is not in extended format, or is in extended format with a stripe count of 1, CLOSE releases space only on the current volume. Are you using extended format? Or do you have dynamic volume count, or guarantee space? Many things to check. These are a couple of them. You could also have: Partial Space Release will release unused space with a sequential file at DFSMShsm Primary Space Management time. This is specified in the MGMTCLAS assigned to the dataset.

(I am familiar with how ISPF 3.4 reports space in tracks even though the dataset may be allocated in cylinders. So a dataset reported as 150 tracks, with 5 occupied, might be expected to come down to 15 tracks, not 5.) They are utterly vanilla PS FBS 27920. The ISPF F command error says "The data set that this command has been issued against is a multivolume data set. The command is invalid for multivolume data sets." ???

The F (FREE) command in ISPF will do this. Caveats. DSORG will also control what can be released. If there is a PSU, DA, or others (I do not remember which ones) the Free may not work. If the dataset is a PDS it may have GAS, so you need to compress it before you can free the unused space.

LOL These datasets definitely occupy space. A typical dataset is 150 tracks of which 5 are in use. The volume list shows as CCXZ08 * * so presumably all of the 150 tracks are on CCZZ08 and that is where I want to release space (not on * and *!). ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
