SORT can also process a concatenation, so it can be more than one input file. It might even be able to access multiple DD's, but I didn't crack the manuals to look this one up. I always thought EQUALS was still valid on a MERGE, so I pulled the manual... "When specified for a MERGE application, EQUALS guarantees that whenever equal-keyed records appear in different SORTIN data sets, the record from the lowest numbered SORTINnn will be written first to the output file." ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
