Re: Chacteristics of HOME ASC mode
What if you Have a ss pc rtn and want to access data and inst from the program that issued the ss pc rtn Home is not where the issuer of a ss pc came from necessarily. Consider if home PC'd to ASID P which then PC's to you. The data from the issuer of your PC is not in home but in P. As has been described, ALET=1 in AR mode works for that case as long as your PC routine is defined properly.. If you need the home space (for example to examine the current TCB), then ALET=2 is appropriate to use. If you were to switch to home ASC mode to look at this, your code would have to be in common storage. Very few documented system services (if any) work in home ASC mode. If they do not say they do, then do not use them in that way Peter Relson z/OS Core Technology Design -- 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

Re: Chacteristics of HOME ASC mode
Accessing *data* from the caller of a PC-ss is easy - just use SASN=OLD on the ETDEF and then ALET of 1 in AR-mode to address caller's data. Why do you need to execute *instructions* in the home address space from a PC-ss?
