Depending on how much data you actually want to look at and/or change,
you might actually be wanting a tied hash, the thing perl4 had dbmopen()
for. Now, you could think of using some DBM package (SDBM, NDBM, etc),
BerkeleyDB, or DBM::Deep. I'm not sure what exactly is available for
MacPerl, but I think that is the route you should try out.
