I have been thinking about this. And what you said jogged my memory... In order to get around this problem, way back when, I used a BUFFER length keyword and specified 32760 or something like that on the first DD statement. Then it didn’t matter which PDS was specified first.

If the first library has the larger BLKSIZE, then smaller subsequent libraries will have no impact. As for LPA, Linklist, etc., these have no bearing on JOBLIB/STEPLIB. BTW, what error is being received?

Did the JCL change? Did the blksize of the 1st dataset in the JOBLIB concatenation change? ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu<mailto:lists...@listserv.ua.edu> with the message: INFO IBM-MAIN American Express made the following annotations "This message and any attachments are solely for the intended recipient and may contain confidential or privileged information.
