Help with running RT-11 SAV files under RSTS/E

You are correct. The problem is when VBGEXE.SAV is used under a mapped RT-11 monitor (RT11XM) to load and initiate MACRO.SAV, especially for a system job. If RSTS/E looks like an SJ environment, then it should provide that information to an RT-11 request to determine if a mapped monitor is being used. That will be PERFECT since the problems can occur ONLY with a mapped RT-11 monitor. Can anyone verify that the CONFG2 (location 300 offset) word will show an unmapped monitor? This is extremely easy to verify. Assuming that an RT-11 distribution is available, an attempt to: SW RT11 RUN VBGEXE.SAV under RSTS/E will generate the error message that a mapped monitor is required as the very first bit of code that is executed if RSTS/E looks like a SJ monitor as far as any RT-11 program is concerned. VBGEXE.SAV is available with all RT-11 distributions starting with V05.01 of RT-11. Probably the best distribution to use is V05.03 of RT-11 which is available at: http://www.classiccmp.org/PDP-11/RT-11/dists/ There will still be the problem of extracting VBGEXE.SAV and placing the file into the RSTS/E environment. But anyone running RSTS/E under an emulator should have very little difficulty in that regard. If you run into any problems, I can probably help. Thank you again. I lost track of this file which you told me about almost a year ago. I hope that the file will provide the information. Jerome Fine
