If one browses SYS1.UADS, one will notice that each member name/TSO User ID has been suffixed with the character '0'. Since the maximum length of the member name is 8 bytes and since ACCOUNT adds a '0' to TSO User ID, the maximum length of a TSO User ID is 7.
At least, this is what I have gleaned over the years. ---------------------------------------------------------------------- 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
