If you want to set the XTITLE to read, for example: Wavelength (A) (with
the A being an Angstrom symbol, try:
...,XTITLE='Wavelength ('+STRING(197b)+')',...
This should work, if you are using vector drawn fonts (FONT=1).
I believe the output for the various hardware dependent postscript fonts
depends on the particular font you are using, but you should be able to
use the same method to get whatever character is defined for that
particular ascii value for that particular font.
Hope that helps,
