g77 compiler

Nonmem users: I am re-installing NONMEM V using a g77 compiler (in lieu of the Digital Fortran compiler previously used). I have reviewed the NONMEM Users Tip # 12 and the information in the NONMEM archives, I am still receiving an error message and I suspect that the below listed lines in the nmfe5,bat files are the source of the problem set dir=c:\nmv set f=ifort set op=/nologo /nbs /w /4Yportlib /Gs /Ob1gyti /Qprec_div I changed the "set dir" to the g77 directory and I think that I need to change the "set f" to g77. But I don't know what switches to use in the "set op" line. Can anyone suggest the correct command?
