Whoever invented the notation "n for an octal constant should be taken
out and shot, or at least go through an extreme de-tox treatment to
remove whatever substance must have been influencing them at the time.

Consider this cornucopia of consistency:

IDL> a="12
IDL> help,a
A INT = 10
IDL> a= "18
IDL> help,a
A INT = 1
IDL> a= "81
IDL> help,a
A STRING = '81'

not to mention that all those loose double-quotes really mess up
string formatting. I recommend the far more sensible:

IDL> a='12'O

possibly coupled with a stern note to ITTVIS suggesting they provide
an option to disable the former brain-dead notation.
