You are right.  (I only used 5.0 under DOS and I had forgotten that it
came with OS/2 libraries).

No disagreement there.

BTW, I tried again; I got an answer 1. both under OS/2 2.0
and under DOS 5.0 with both compilers (For Watcom, using DOS4gw).

I am inclined to believe the other poster (sorry, forgot his name)
who says it may be hardware-related.

But in my case, it's not an issue of the known bug in some 486
motherboards: I am running this on a 386-25 (an old Mylex motherboard
that I have normally found quite reliable) and (*here it gets
interesting?*) an IIT FPU *not an Intel*.

(It's all Dov's fault :-)...  He called some evil spirits upon
us by posting all that Fabrikant's literature...  :-))
