The PREFIX option allows you to change the prefixes of the DSNAMEs that MAXSORT generates for the intermediate output data sets.
The last character specified must always be a period, and a maximum of 27 other characters may be coded unless the TIMESTMP option is also specified. If TIMESTMP is specified, a maximum of 18 characters plus the final period may be used. TDS. is the default name.
The PREFIX option can be overridden by the BKPTDSN PARM at execution time.
