Thank you so much, Dr. Fanning, for taking the time from your busy schedule to edit the CheckForSymbols program. It even fixed my issues with an errant postscript output of my plots with the greek subscripts!

I have added the ability to use Greek characters as subscripts or
superscripts to the Coyote Library. In this example, you would formulate
the text like this, using the "\\" symbol to indicate the Greek letter
to be used:
cgPlot, cgDemoData(1), XTitle='$\Omega$$\sub\\lambda$', Charsize=2.0
To create a superscript, you could do this:
cgPlot, cgDemoData(1), XTitle='$\Omega$$\up\\lambda$', Charsize=2.0
You will need to update your cgCheckForSymbols program:

Hi Dr. Fanning,
Thank you for your prompt reply and help with my problem! It works for now and I can use it for my assignment.
I greatly appreciate it, and I hope you have a wonderful evening and a great rest of your weekend!
Best,
Harish

Well, this is complicated. :-(
I'm going out for the evening, but this should get you going, I guess:
IDL> print, cgSymbol('lambda')
!4k!X
IDL> cgplot, findgen(10), findgen(10), xtitle='$\Omega$$\sub!4k!X$'
The problem is a substitution inside a substitution. The software is not
set up currently to handle something like this. I'll see what I can do
about it later.
Cheers,
David
