Another possibility, which might be an option for batch
processing, is to use environment variables.
a la
exe='/x/y/z/idlrt.exe studyeval.sav'
export study="study1"
eval $exe
export study="study2"
eval $exe
...
and in studyeval.pro
; setenv, 'study=study1' ; for testing
study = getenv('study')
For user interaction this approach might be a bit cumbersome, though.
Cheers
