What infuriates me is that when I want, e.g., 1GB (a reasonable amount given that I can carry terabytes in my shirt pocket), I must factor it into U, K, or M (why no "G", even "T"?) rather than the intuitive BLKSIZE=0,SPACE=(1000000000,1).
I'm not sure whether this is intended use, but it seems to work the way I would expect:
//DD1 DD DISP=(NEW,CATLG), // DSN=ANDREWR.TEST.DATASET, // SPACE=(2,(3,4)),AVGREC=M, // LRECL=80,RECFM=FB,DSORG=PS,BLKSIZE=27920, // UNIT=SYSDA ISPF 3.4 dataset information shows: Organization . . . : PS Record format . . . : FB Record length . . . : 80 Block size . . . . : 27920 1st extent megabytes: 6 Secondary megabytes : 8 So to allocate in GB I can do: // SPACE=(1000,(1,1)),AVGREC=M, which gives me 1GB primary, 1GB secondary: Organization . . . : PS Record format . . . : FB Record length . . . : 80 Block size . . . . : 27920 1st extent megabytes: 1000 Secondary megabytes : 1000 -- Andrew Rowley Black Hill Software ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
