[Getdp] Launching GetDP from another program

[John_V]

The problem with launching the batch file turned out to be that Windows 
doesn't natively know how to launch batch files. The operating system 
doesn't know what to make of "FEA.bat", but "cmd /c FEA.bat" works. 
(I.e., launching a batch file is an option of the "cmd" command.) I am 
still not sure why the method I first tried, directly sending "getdp 
-pre EleSta_v.pro -cal", didn't work. I may investigate at some point, 
but doing it via batch file is an acceptable work-around. Thanks to all 
who helped: Joris, Lars, and Ruth.
