OrbWin is a replacement for the outdated OrbWeaver.

OrbWeaver was an interactive editor for 2-D spherical-shell
finite-element grids, written in Microsoft BASIC for the DOS operating system.
The executable version ORBWEAVE.exe could also run under Windows;
however, the 640 KB limit on memory, resulting from the kludgy method of
memory addressing under DOS, remains in place.

For this reason, Zhen Liu and Peter Bird rewrote the program
in Compaq Visual Fortran 6.6A for Windows (32-bit versions, such as:
Windows 95, Windows 98, Windows ME, Windows NT, Windows 2000, Windows XP, Windows Vista).
This new program is called OrbWin (latest version: v1.1 of 2010).
It allows access to very large amounts of memory (up to 2 GB?),
with the proviso that the user has to anticipate the size of the grid(s)
that will be edited in any work session, and allocate storage at the start.
(It does no harm to allocate more storage than needed.)

We hope that future 64-bit versions of Windows will support 32-bit
executables like OrbWin.exe, but this remains to be seen!

OrbWin also supports the 2 additional nodal data added in the 
2006.08.29 version of Shells:
-compositional density anomaly of the entire lithosphere;
-non-steady-state curvature of the geotherm due to transient cooling/heating.

Another generalization of function is that OrbWin now explicitly
supports the slightly-different variants of .feg file structure that
are needed for my kinematic F-E programs NeoKinema and/or Restore
(e.g., no fault elements; different nodal data fields).

Because of this increased functionality, /OrbWin/ has been placed
here at the root of the /oldFTP/ directory structure,
instead of appearing next to /OrbWeaver/ within /oldFPT/neotec/SHELLS/.

If you need to modify the source code and recompile, I wish you luck!
The complexity of file, resource, and library networks under the newer
Compaq/DEC/Microsoft "Visual ___" compilers is very daunting to those who
are not professional programmers!  
I have attempted to capture all the necessary
files within this folder.
I hope nothing essential is missing.  
(In fact, I may have included some files that are not needed,
   but is difficult to be sure.)
