The S/360 had a push button on the console labeled "External Interrupt". I don't recall ever using it (but that would have been in 1970-71).
When generating a SA DUMP IPL test you can list a series of addresses For the console it is to use. In this case, providing an "External Interrupt" by pressing a key on the keyboard wakes up the SA dump program and identifies which of the consoles is to be used for operator interaction. I think SAPL is a VM function. That's how interpret the wording in the ICKDSF manual. It says see the VM/ESA Planning and Administration manual for more info in the SAPL. -----Original Message----- 1. What is EXTERNAL INTERRUPT key ? I've seen it in description of SA DUMP. The book title is MVS Diagnosis: Tools and Service Aids. 2. What is SAPL ? Stand Alone Program Loader is mentioned in ICKDSF manual. However coldn't find any reference. -- Radoslaw Skorupka Lodz, Poland ---------------------------------------------------------------------- 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
