Hi,
regarding Option 1:
Try compiling your file:
resolve_routine, 'PS_GS', /compile_full_file, /either
resolve_all
save, /routines, 'yourDirectory\ps_gs.sav'
Then try calling
subprocess.call("idldirectory\idlrt.exe yourDirectory\ps_gs.sav")
This works on my pc. I don't have Envi to test it though... I made a simple file with just
p = plot(/test)
inside and it works.
I didn't test the call from python, but it works from the command line.
Cheers,
Helder
