Dear all,
I`d like to print large brackets in a PostScript file. I think the best
idea is to use the Symbol Font and the "bracketlefttp",
"bracketleftex",.... characters. How do I have access to them under IDL?
Is it possible to use the octal encoding?
I dont know what to type on the keyboard. I use IDL 5.1 under SuSE Linux
5.3
Lothar

This takes *all* the fun out of adding octal codes to
your programs. I'm *completely* against it. :^)
And a Merry Christmas to you, Sir!

Soapbox: May I recommend that *nobody* use double-quote octal codes in
their new IDL programs. They are abominable to look at, can be
ambiguous, and are confusing. The fact that the second quote never
appears is particularly insidious.
The "single-quote" form is not much better, but at least it is
consistent in the sense that there are two matching quote characters.
These two expressions perform the same operation:
a = '355'OB ; SINGLE QUOTE FORM
a = "355b ; DOUBLE QUOTE FORM
I believe the first form should always be preferred.
