They are allocated in tracks. (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
