[Mesa-users] f90 modules in f77

[Travis Metcalfe]

Hello,

I'm looking for a way to share data between some older f77 code and the 
MESA/GYRE modules. In f77, subroutines could share data with each other 
through common blocks. This appears to be replaced with modules and "use 
[module name]" in f90.

What I have been unable to find online or in the mesa-users archive is how 
to use an f90 module from an f77 program. Is it possible?

Thanks,

Travis
