I have 197 common blocks included from dedicated files and a massive

are actually in the common block files.  The equivalences have made the
eventual C++ conversion of the Fortran code tricky.

 What do you use the equivalences for?  Saving memory? Then this
should not be a large issue on modern machines.

About the only thing I've used it for is for performing mathematical operations on things like characters for encryption or compression algorithms.  Using a function for that doesn't appeal to me.

 If you are using them for tricks with type conversion, then you
are on thin ice already, and have been since Fortran 66.
 And if you have a few big arrays, then changing those to ALLOCATABLE
and allocating them at runtime might well be straightforward.
