Billy D'Augustine in a message of 9-Jan-91 inquires about the compatibility of RSX task images and the P/OS operating system. RSX-11M-Plus supports two variants of task headers; resident and nonresident. Without going into unnecessary detail on the differences between the forms, only nonresident header task images will run under P/OS. M-Plus permits overriding the header form with the INStall switch /XHR=(yes, no) but P/OS does not support this. Therefore, any task image brought into a P/OS system from an M-Plus system must have been built with the TKB /XH switch to force external headers. The usual symptom of this problem is that P/OS complains with an error message of the form: INS -- Task has a resident header Glenn Everhart very correctly also points out that Kermit does not create a contiguous file, and that PIP /NV/CD/CO must be used to create a new, contiguous task image from the received file.

Many thanx to the people who replied to my question about running RSX tasks under P/OS. And my apology for replying publicly to the net (our mail router isnt functioning properly; I can recive mail, but cannot reply) Anyways. The command PIP FOO.BAR/CO/NV=FOO.BAR works just fine. I assume that the /CO stands for CONTIGIOUS, waht does the /NV stand for? (btw: I accomplished this using the DCL command COPY/CONTIG, which I assume spawn PIP with the above parameters) Now comes the fun part:-) Trying to build up a software base. An unfortunate observation. It seems that quite a bit of tasks need a resident image installed in memory to run, and some look for other task files. When P/OS aborts, it doesnt specify _which_ file it is looking for. For instance, a version of ADVENTURE aborted with some mumbo jumbo, and reported a directory spec: [001001], which I would assume is looking for some kind of message data base. (dont bother trying to make sense out of this psycobabble:-) I am just making an observation) Does anyone have the DECUS P/OS sig stuff? Theres quite a bit of stuff for the P/OS listed in the Pro 350 section. But unfortunatly, I cannot justify spending over $200 for this software Billy D'Augustine billy@westmark.com ^^^^^^^^^^^^^^^^^^
