OK, here is a routine that does this, but it is
totally illegal, bogus, etc., and you didn't get
it from me. :-(
You will need my UNDEFINE program to make it work
elegantly. If you don't need elegance, just delete
that line.
;****************************************************
PRO Help_Var
; Just print out the damn variables!
names = ROUTINE_NAMES(Variables=1)
FOR j=0, N_Elements(names) - 1 DO BEGIN
IF N_Elements(ROUTINE_NAMES(names[j], FETCH=1)) GT 0 THEN BEGIN
value = ROUTINE_NAMES(names[j], FETCH=1)
HELP, value, Output=s
UnDefine, value
Print, StrUpCase(names[j]) + StrMid(s, 6)
ENDIF
ENDFOR
END

Yeah, well, if you need to do this, I'd guess the chances
are probably better than even you need some work on
your programming style. :-)
But I leave it as an exercise for the reader to develop
a method that can use regular expressions to search out
variables for deletion. I can't think of a way. I'm
pretty sure that even this hocus-pocus isn't strong
enough magic to do it.

Oogh. This makes all the effort worthwhile! Thanks. :-)
Cheers,
