Sam, Almost….. in the beginning there was sys1.uads 7 character ID . Then if you wanted to have a special accounting info etc and there was only so much space (IIRC 800 bytes) if you needed multiple accounts and accounting info etc the ID was extended until (I think 800 bytes) then in order to allow additional accounting info etc another “id” was created so instead of pepper an extension (new member) was created called pepper1 and so on and so forth until pepper9 so, if memory serves me everybody had a pepper0 then depending on accounting info etc the next “id” was pepper1 etc etc pepper9. Its been a while so that first ID ended with hex zero then the second was 1 (this part here I am iffy on) as we only had 1 or 2 that had the added character. I just don’t remember of it was hex 00 then hex 01 or if it was a character 1 then 2 etc,, ED ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
