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!
