Fails for me on IDL 6.2 on Linux, the problem seems to be that the
.reset_session is throwing away the path additions when called via @

If I issue the 3 commands:

if (strmatch(!PATH, '*allan*') eq 0L) then print,'1'
.reset_session
if (strmatch(!PATH, '*allan*') eq 0L) then print,'2'

then nothing gets printed but if I put them in an file and call it via @
then I get '2' printed to the screen (I had something with 'allan' added
to my !path variable).

The root of the problem is that the startup file gets processed straight
after the .reset_session when called from the command line but if a
.reset_session call is inside an @file then it's reprocessed after the
whole @file is finished.

I'm not sure if this is the correct behaviour or not (one would suspect
not since David found a different behaviour on windows).

The pragmatic solution is, I guess, to rebuild your path or manually
call your startup file after the .reset_session.

Hope this helps.

Thanks,

Allan
