Lua & external DOS executable applications

["ac090960 <ac090960@xxxxxxxx>" <ac090960@xxxxxxxx>]

Hello, 
First of all Happy New Year,

I wondering if is possible to run external applications ( DOS 
executables compiled from FORTRAN codes) inside a LUA session.
I mean: is it possible with a LUA script run iteratively a FEMM 
problem calling after a femm calculation a DOS application ( xxx.exe) 
(e.g.: the application able to manipulate some FEMM output) and then 
( after a FEMM geometry modification) run the new femm problem and so 
on?

If it is not possible make this external call in LUA are there any 
other way to run iteratively FEMM "linking/calling it" with 
external DOS applications ?

Any help and suggestion on this matter ( linking & calling FEMM with 
DOS application) is welcome

Thanks in advance for reply,
Arnoldo
