Two things to look at:

1.  The +E compiler switch, if I remember correctly, causes ALL global
symbols to become external.  I think it is on by default.  Since you
have so many global symbols, you might want to try turning it off and
explicitly declaring just those you need. 

2.  You can get by with only one global variable by defining a record
with 97 fields and having one global variable of that record type.
But a much better style is to organize them into related groups of
variables, and to make each group a structure with an associated
global variable of that type.  This should make the program much
cleaner and easier to maintain.  Having done so, you might then decide
that it is no longer so onerous passing around these structures as VAR
parameters and get rid of the global variables altogether!
