Example of bat file to run Nastran for every *.dat file in the current folder 2

[gantovnik]

This is example of Windows bat file to run Nastran for every *.dat file in the current folder.
It also calculates the total Nastran execution time. Of course, you should change path to nastran.exe. The nice thing here is that script uses variable set MyPath=%cd%, so you don't need to enter path for *.dat files Enjoy!

@setlocal 
set start=%time%
set MyPath=%cd%
