I am having a problem with Mince on MP/M-II that I can't figure out how to fix
and I wonder if anyone else has any idea (I may have fixed this at one point
but can't remember how or if I, in fact, did).
I am running MP/M-II on an H89 with Magnolia's 128K board. I have half of
the Z67 as my A disk. I have a MINCE.SWP in user 0, SYS, RW. All works
fine in CP/M. In MP/M, when I try to run from (e.g.) user 12, when swapping
gets done, I get the BDOS error message that a write is being attempted to
a file opened R/O. Reading the MP/M documentation, it appears that doing
a default open on a file in user 0, even if the file is RW, the open is done
R/O.
I tried all four compatibility attributes even though the documentation didn't
make it sound as though they were the problem and, in fact, they didn't do
the trick.
Anyone have any ideas?
