I can't check right now, but I'm pretty certain that we run GAP with
'EMM386' in 'config.sys'. Somewhere in the documentation for 'djgpp' it
says that you cannot use the 'noems' switch, whatever that means. Also I
think that if GAP has problems with the memory manager it would not even
start, while you report that the problems appear once GAP tries to read a
file. Of course if GAP now works in your lab, you may not want to
experiment further (if it ain't broke ...), on the other hand I wonder
how much memory GAP can use if you run no memory manager. Maybe only 640
kByte, and when it needs more it starts paging (ouch)?

PS. I have this theory about why Bill Gates is so rich. Secretly every
programmer who makes a living from writing a program that fixes a problem
or a deficiency in MSDOS has to pay Bill Gates 10% of his income. Well
maybe it's only 1%.
