But it explains why I've experienced no BLKSIZE problems lately in concatenations, despite not being very diligent about order or overrides. BTW, I noticed post facto that in my successful test I had coded BLKSIZE=32760. That's not even a multiple of 80. -- gil ---------------------------------------------------------------------- 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
