PoOps describes the DAT facility, but it doesn't, and shouldn't, describe who implements it. Like DAT, PC, PR et al are black boxes; you are supposed to program to the architecture, not to the implementation on any specific model.

Yes I agree that PC doesn't involve any interruption. "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
