'
A couple of useful extended macros made their way into the system a while back -- some of them from JonLs package.'
'
The ones I like (available under control-Z in DEDIT) are':'
'
IFY  (turn COND into IF)'
BQUOTE (turn LIST/CONS expression into BQUOTE)'
'
there are probably more goodies there too. I''m actually a little reluctant to publish these since they''re not necessarily ''generally useful'' enough to clutter up the name space.'
'
Opinions?'

     I guess you already know that I and some others think there are some'
things wrong with ASSIST''s backquote.  Advertising your BQUOTE macro'
before the choice of ASSIST''s backquote versus <LISP>LIBRARY>BQUOTE is'
resolved could cause extra confusion if it is decided to back out of the'
ASSIST version.'

I''d certainly prefer to see COPY and SWITCH as standard -- the IFY and BQUOTE edit macros are very low on my list (same probably 99% of other users).  '
'
What I can''t understand is why Interlisp 10 years ago didn''t have the equivalents of COPY and SWITCH -- both have the same syntax as the the MOVE command (i.e., generalized location specifiers separated by a "noise" word such as TO or WITH).'

IFY and BQUOTE (like GETD and MAKEFN) are examples of commands that are still quite useful in DEdit, using the control-Z escape.'
'
SWITCH and COPY aren''t very useful in DEdit, which is why I didn''t advertise them.'

Is the "horse before the cart here"?'
'
IFY and BQUOTE editmacros are not useful if no one uses them.'
'
If the Teletype editor is stil supported (Chapter 17 of manual) then SWITCH and COPY ought to be documented and "advertised".'
