No, it's not true. IDL has always been case insensitive.

Find the SET_PLOT, 'PS' line. Just ahead of that like put this:
thisDevice = !D.NAME
Now replace the SET_PLOT, 'X' line with this one:
SET_PLOT, thisDevice
Now your program will work on both LINUX and Windows computers.
Cheers,
David

First, IDL is case insensitive, so the variables *BIDS* AND *bIDS* in
your code are no different, but the later one will overrides the
previous one. For eample:
PRO CaseEx
BIDS = 10
bIDS = 20
print, BIDS, bIDS
; // 20, 20
END
Second, the procedure *set_plot* is used to set your output device,
find out more details by entering *? set_plot* in the idlworkbench
commandline.
Moreover, if you could paste your code out, it will be helpful.
Good Luck!

Hi,
set_plot,'x' is used to set the device in linux, change it to
set_plot,'win' for windows machine.. it should work, well it works for
me...I guess what Dr.Fanning says is a generic solution..I will
implement that in my codes as I always change it while changing my
linux written programs to windows version. Thanks.
regards
Sajan.
