Actually, in the most current version of PV-WAVE CL/Advantage (4.20), the ? is no
longer a help command. It now responds with:
% To get online help, use the HELP command.
HELP calls up really fantastic new on-line docs (and for the near future, will
also do what HELP used to do).
INFO is the new command to do what HELP used to.
A bit of a pain, at first, but the new command names make a bit more sense to me.

Back to the issue at hand,

Bill Thompson's suggestion of using
GETENV('WAVE_VERSION')
is pretty good, except that WAVE_VERSION is not strictly required
(it's set in wvsetup, but some goofy sys.admin could whack it).
I think all of the WAVE environment variables are optional, strictly speaking.

How about looking for some standard file that's included with one but
not the other, like:

is_wave = FINDFILE(!Dir+'/bin/wave') NE ''

Of course, you gotta dink with it for VMS....
