I changed malloc to calloc in exeload.c and
the problem was resolved. I didn't notice a
specific BSS section in the LX header so will
leave any refining of that to another day.

My theory of how I could get files working
for DOSCALLS appears to be correct - I can
indeed turn them around back into FILE accesses,
except if the handle is less than 3. Quite
neat result for 200 lines of code so far.

I will defer fleshing out DosDevIOCtl in terms
of setvbuf plus others until some other things
are resolved (bug reports, compiler, pdld,
microemacs makefile).

New pdos.zip etc uploaded.

BFN. Paul.
