You cannot run a batch job with the same name unless you logoff and back on to allow the 8 character batch job to run. Thus, the 7 character userid allows an extra character for batch job submission. I'm sure the UADS userid with the '0' appended to the member name might have had something to do with it as well...

The limitation of 7 characters for TSO IDs has caused us extra work in the past (we use IDs of 3-8 characters across the institution, but the mainframe can't use the institutional IDs in part because of this limitation). What is the underlying technical reason for the restriction? Thanks for any insight. ---------------------------------------------------------------------- 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 ---------------------------------------------------------------------- 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
