Subject: NONMEM V and Power Macs

I am currently attempting to compile NONMEM V using Digital Visual Fortran (Version 5, standard version). I am using a Power Macintosh G3 (32 Mb RAM) with "Virtual PC" software running Windows 95.

Using "setup.bat" under DOS, I get an error message when at Step 6b of the compilation, apparently when attempting to compile subroutine REXPON. The error message comes from Windows and reads:

"A fatal exception 0D has occurred at 0028:C00027F0 in VXD VMM(01) + 000017F0"

It occurs both when virtual memory is switched on and when it is switched off.

I do not think this is due to an inability to compile double precision as a test program suggested by Alison Boeckmann worked fine.

Can anyone shed any light on this problem?

Is it likely to be corrected by additional RAM?
