Hello everybody,
I would like to get information about how to compile fortran subroutines
in C programs an vice versa. I have managed to do it with small programs
in both directions. My problem is with common blocks, I don't know how
to access them from a C function.
For example, if I have a fortran MAIN program:
PROGRAM TRY
common/block/A,B
.
.
.
END
How can I have access to A and B from a C subroutine to manipulate them?
Thanks in advance.

Sorry, I fogot to say that I'm using gcc and g77 in RH6.0. just in case
it is important. Thanks again.

As g77 falls squarely within the f2c style of fortran implementation, in case
of question you could use f2c to translate into gcc. I would expect
extern struct{float A;float B;}block;
