You probably want something like (NumRegsPed * sizeof(char *)) instead of
100.

Yes. You've allocated an array of pointers.

No, but you'll have to keep the record's handle locked. You can't
dereference a pointer once it's handle is unlocked.

No. Freeing an array of pointers won't iterate through the pointers. You'll
have to do that yourself.

You're effectively copying the entire database into the dynamic heap. This
probably isn't a good idea. Dynamic heap space is limited, so you should try
to work directly with the database. If you have to, copy a single record to
the dynamic heap while it's being edited.
Hope this helps.
