The 360/20 was a 16-bit machine which had BAS/BASR, which I used a lot at the time. The 360/20 did not have BAL/BALR which I started to use on 370 systems in 1975. IIRC, early 370 systems didn't have BAS/BASR, which were added to XA systems. Sorry for the error. -- Gilbert Saint-Flour GSF Software http://gsf-soft.com/ ---------------------------------------------------------------------- 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
