My application is neither DOS nor Windows, but is an OS/2 32-bit native
application. I expected that it would work as under 2.1, and it should. But
why???, I dunno...yet. I consider this very serious.
In case I misunderstood your comment, under OS/2, I am running an OS/2
application. But I want to toggle (using Ctrl-Esc) to a Windows
application, and vice-versa. On my system, I have installed on C:
my MS-DOS/Windows, on D: my OS/{at} 2.1, and on F: my Warp. Via BOOTMANAGER
I boot to WARP. I understand that WARP should enable me to transfer
control to MS-Windows, even though I have not booted to the DOS/Windows.
Re FORTRAN, it still runs slowly, even when compiled with Watcom's latest
Fortran compiler, and optimized for the Pentium. BTW, you have a good
memory...it's has been 6 months since I first sought assistance.
