This is not a concern. The databases are compatible from 8-bit to 64-bit
and beyond. MUMPS is an architectureless model that translates well across
all of the different arcitectures once a MUMPS is compiled for that
architecture.

In view of posts in this thread about GT.M and free software, a few

Apropos the discussion on free software, the intention with GT.M on x86

There are two issues here: (a) what GT.M does and does not allow, and
(b) the application logic, which includes the execution settings.
GT.M allows you to use any arbitrary sequence of bytes both as an index
