Re: [Aptos-devel] APT-AC ???

OK, thanks, this is good info, an IBM APT product that was in common 
use at aerospace companies at the time. Does this relate in any way 
to the "other" APT lists in existence? 

It was my understanding that the Apt4ssv3 list (on Assembla.com)  
was for rewriting the APT4 v3 Fortran source code, which was said to 
be available without copyright restrictions. And that the apt4ssx8 
list (on freelists.org) was for rewriting the APT4 v8 Fortran source 
code, which was said to be available, but was still covered by some 
copyright (maybe NASA?) but that someone was working on getting them 
to release it into the public domain.  However, there have been no 
substantive posts on either list for 1 year, and 3 years, respectively.

The delay (as I understood it) was to wait and see if the APT4 v8 code 
could be freed up, and if so, to start with that. But if v8 could not 
be freed up, then to start with APT4 v3. 

What is the origin of APT360, would that be APT3? Any possibility of 
getting either of the two APT4 projects moving again? Or, the APT4 
improvements (if any?) merged with APT360? Or, something else? 

Any information, ideas, suggestions, much appreciated.
