JCL has similar archaic restrictions. Why not code BLKSIZE=0,SPACE=(10000000000,5000000000) -- (10 GB primary, 5 GB secondary), amounts very reasonable with modern DASD, and let the OS make the determination of blocks, tracks, or cylinders? Programmers focused on foreign systems such as the OP shouldn't be burdened with knowing details of IBM DASD geometry. And why does the ridiculous limit, "Syntax allows for values of 0-16777215" persist in an OS running on 64-bit hardware? --gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
