General coding notes
- A SORTINnn data set should not be the same as the SORTOUT data set or any OUTFIL data set because this can cause lost or incorrect data or unpredictable results.
- You can merge up to 100 data sets with Blockset merge or up to
16 data sets with Conventional merge. If Conventional merge is selected,
check message ICE800I for the reason Blockset could not be used and
correct the indicated condition, if possible.
- With Blockset merge, nn can be any integer from 00 (the initial
zero is optional) to 99, in any order. Blockset merge treats ddnames
of the form SORTINn and SORTIN0n as duplicates, and ignores any occurrences
after: the first. For example, if you have
the SORTIN04 DD will be ignored.//SORTIN4 DD . . . //SORTIN04 DD . . . - With Conventional merge, nn can range from 01 to 16. The first number you use must be 01 and the remainder must follow in numeric order. Numbers cannot be skipped. Conventional merge cannot use ddnames of the form SORTIN0-SORTIN9, SORTIN00 or SORTIN17-SORTIN99.
- With Blockset merge, nn can be any integer from 00 (the initial
zero is optional) to 99, in any order. Blockset merge treats ddnames
of the form SORTINn and SORTIN0n as duplicates, and ignores any occurrences
after: the first. For example, if you have
- FREE=CLOSE cannot be specified. User labels are not copied.
