Hi,

Verb READ does a sequentail "process", it doesn't understand whether you want to skip something in between. I can think of two appraoches..

1. Make a separate file with thes ealternate records using File-Aid/SORT & use that file as an input.

2. READ the file in a COBOL table, work on that table for further processing.

Sort INREC append a sequence number and INCLUDE only those you want?
