I seem to remember that once I read something somewhere (maybe on alt.sys.pdp10) about certain cases in which ANF-10 support couldn't be excluded even if unneeded. So I tried a build with it and I obtained NO undefined symbols. I have no way to test the resulting monitor, but maybe it could work. BTW, I noticed that even with those seven undefined symbols the executable file got created anyway, so maybe they are not really needed for the monitor to work... I Don't know.

My gess was the distributed TOPS10.REL does not contain all the required modules, so it should be rebuilt somehow. The "A" appendix in the software installation manual is supposed to explain that, but it has not been of much help... No, I'm quite sure about this: as long as you build a monitor with a standard set of features, you do not need to rebuild TOPS10.REL from scratch. The Software Installation Guide is quite clear about that (page 9-16): | If you are using a standard combination of feature-test switch settings and | DIGITAL-supplied sources, you do not need to assemble the remainder of the | bundled monitor modules. These modules have already been assembled and | combined in a monitor library file named TOPS10.REL. | [...] | If you are not using a standard combination of feature-test switch settings | or if you have made changes to the monitor sources, you must assemble all | the monitor sources, creating a new monitor library file. http://pdp-10.trailing-edge.com/tops10v704_docc/01/10,7/docupd/sig.mem.html Let's hope that the ANF-10 trick is enough! :) G.
