The IGZSRTCD data set is optional. Its defaults are LRECL=80, BLKSIZE=400, and ddname IGZSRTCD.
You can use a different ddname by coding it in the SORT-CONTROL special register. If you defined a ddname for the SORT-CONTROL data set and you receive the message IGZ0027W, an OPEN failure occurred that you should investigate.
