Gaurav,

I have linked g77 objects (.o files) with the Absoft compiler, and I assume
it also works the other way around. Just stick the .o file in the Absoft
compile command. For instance, say you have g77code.f to be compiled with
g77, and abscode.f to be compiled with Absoft F77, linking in g77code:

g77 g77code.f -c
f77 abscode.f g77code.o

Of course, include any other relevant options. The other thing to be aware
of is case sensitivity and trailing underscores. If you name a function or
subroutine as "mysub" in g77, it needs to be referenced as "mysub_" from
Absoft code. Absoft f77 allows case sensitivity, so keep track of that, or
be sure to use the -f (force to lower case) or -N109 (upper case) options.
Absoft F90/95 forces to upper case by default. With Absoft F77, you can
globally append an underscore to each subroutine/function with the -N15
option if that's easier than naming them manually.

I have not linked Absoft objects into g77, but they are obviously
compatible, so it should work.
