I've been going through some of my manuals, and in looking at the Macro-11 manuals it looks as if they're pretty much written with the intention of being used with any of the DEC OS's. Is Macro-11 pretty much the same across the various platforms or what? If so, what makes a program written in Macro-11 a RT-11 program instead of a RSX-11M program other, than the way that it is linked? Zane | Zane H.
