Try using "g77 -c aa.f" to generate the object file "aa.o". I haven't
used g77 but I suspect that "g77 -o prog mainprog.c aa.o" will then
allow you to create an executable program. Here "mainprog.c"
represents a FORTRAN program that calls the subroutine in "aa.f" and
"prog" is the name of the executable program.
