Ok, so this is equivalent to this:

IDL> str = 'This is the greek symbol epsilon: ' + $
'!9' + string("145b) + '!x'+ '.'
IDL> xobjview, obj_new('idlgrtext', str, /enable_formatting)

In this case, epsilon is represented as the octal value "145B.
I found this value by looking up "true-type font samples" for
the Symbol font in the IDL on-line help. This formulation will
also work for other greek symbols. For example, here is a
capital omega:

IDL> str = 'This is the greek symbol capital omega' $
+ '!9' + string("127b) + '!x' + '.'
IDL> xobjview, obj_new('idlgrtext', str, /enable_formatting)

This will work with *any* Greek symbol. (At least the ones
I've tried.)

Possibly we have the start of some kind of explanation
now. (It turns out, incidentally, that the Times font *has*
a capital omega, but no epsilons!!!!) Weird. How come no one
told me this? That greek page gets downloaded at least a
dozen times a day!! Sheesh!

Cheers,

David
