Hi all, since it is mandatory to declare all subroutines as "external" in Fortran, is it possible for Modules to have subroutines? I'm unable to declare the subroutine external inside the module itself, nor in the program which is using it. Not declaring it external at all results in the following compilation error:
/net/users/csg/csg4035/master/workdir/src/main.F:97: undefined reference to `__grid_MOD_readgrid' (the module is here is named "grid", the subroutine "readgrid" ) Thanks, Leo -------------- next part -------------- An HTML attachment was scrubbed...
