Long ago and far away, a friend was looking at the VSE microfiche and found an undocumented SVC that stored the top half of a register value in the address contained in the bottom half of the register. He promptly wrote a program that used that SVC to gain control of the system. (He was working at IBM, so this was an internal thing.) -- ...phsiii Phil Smith III p...@voltage.com Voltage Security, Inc. www.voltage.com ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
