I think we have a missunderstanding here with the technical side of the volumecount parameter: this is not the way to limit the volumecount to 1.
Default a JFCB area for 5 volumes is reserved if you don't specify a volume count. If this is not enough, you specify a higher volume count and more space for volume information is supplied in chunks of 15. So if you specify vol=(sysda,6) you can go to 5+15=20 volumes, vol=(sysda,25) goes to 5+15+15=35 volumes, And last but not least: vol=(sysda,1) gives you up to 5 volumes. Kees.
