Is there a decent IDE for gnu fortran with gcc ?  I tried Simply Fortran 
and the debugger support is very minimal.  I need to be able to stop on 
the Xth call to a subroutine and Simply Fortran does not support that. 
I have 5,000 subroutines (800k lines of F77), 300 common blocks, and 
500K lines of C++ in over 10,000 files in my calculation engine. 
Managing that without an IDE is challenging.

My Hollerith is gone.  My structures and unions are reduced. The code 
actually converts to C++ fairly well until you get to the formats.

Thanks,
Lynn
