ETCRE et al are part of the setup prior to issuing the PC instruction; the actual implementation of the PC is a black box and need not be the same between models, as long as it complies with PoOps.

First, rather than translation, the PC instruction builds the environment from the token. ETDEF defines the PC environment but ETCRE or ETCON could easily insert calls into the environment entry without us being aware. P/OPS only tells us the hardware side and we don't have access to the internals (e.g. establishing ARR). So the answer is we can't say for sure. Jon.

"Principles of operations" manual clearly explains the PC translation process but I wanted to know "Who" will perform this translation process? For example we have "Dynamic Address translation" facility to transform Virtual addresses, and is there any similar facility to perform PC translation process. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
