I have only TP 5.5, but they are probably all similar in these areas.
The limit for total data is 64K this includes the main program and any units
the program uses.  This does not include any data on the heap, it is limited    only by the amount of memory is installed.  The limit on code is 64K for each   "part".  The main program and each unit get 64K each.  I don't know when it was introduced, but TP 5.5 has a standard unit aptly named OVERLAY.TPU.  The only   problem with OVERLAY is that you can overlay only units, not just any old code. Your olny other option would be to use EXEC (But probably not).
