You need to know what the "string" value of your octal
number is. In the case of the epsilon:
IDL> print, string("145B)
e
So, that is why I can insert !9e!x into the title
string and get it to show up as an epsilon on the
display.
I presume you could do this programmatically, although
I don't have a clue how, by fishing out your axis or
font object (whatever you are trying to change) and
getting the text, manipulating that (you *could* use
your STRING() function now), and putting it back.
I just showed you how to do it with the property sheets.
Cheers,
David
