Example input, RECFM=FB,LRECL=14: DSK001 1009999 DSK002 3962002 DSK003 0001001 DSK005 2009999 DSK006 2009999 DSK008 0100000 DSK007 0001002 DSK004 0527192
Two fields: VOLSER in 1-6 and SIZE in 8-14. I want to assign a 'sequence' number to the input from 1 to 4, so that I can sort these into 4 groups, and within those groups descending order by size: So for this group the input would be modified to have the sequence in 16 (for example) resulting in a temporary work dataset of LRECL=16: DSK001 1009999 1 DSK002 3962002 2 DSK003 0001001 3 DSK005 2009999 4 DSK006 2009999 1 DSK008 0100000 2 DSK007 0001002 3 DSK004 0527192 4 And the final output would be RECFM=FB,LRECL=14 DSK006 2009999 DSK001 1009999 DSK002 3962002 DSK008 0100000 DSK007 0001002 DSK003 0001001 DSK005 2009999 DSK004 0527192 The idea is to "balance" disk backup jobs by spreading the large volumes across the (4) jobs evenly. Doing the sort this way isn't "perfect" but it's closer to what is needed. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
