I don't know if this should be in c.s.a or c.s.a.tech, so I figure I'll
post it to c.s.a since the c.s.a.tech people tend to react more viciously
to stuff incorrectly posted there :-)

I just (finally!) got Arexx (v 1.06 now, upgrading when bill sends the
card) and have been starting to experiment with linking up mg3 and
AmigaTeX and all sorts of other editor goodies.  I've got a few quirks
that I've run into that I'd like some comments on from anybody out
there.  Most of these have to do with the ideas about quoting stuff,
an issue not abundantly clear to me right now.  Experimentation has
led me to the following set of questions (and I did RTFM but no real
help there, yet):

1.  In an Arexx script file, typing 
address 'mg'
    works fine, but typing
address mg
    does not.  

2.  Also, in an Arexx script file, typing 
'rexx-insert "hello"'
    works (inserts hello into the current mg buffer), but 
say 'rexx-insert "hello"'
    does not work; it merely echos 'rexx-insert "hello"' to the shell.

3.  From within mg, the command 
M-x rexx ^M "'rexx-insert' "hi-there""
    hangs mg completely.  (mg bug?  or should I have guessed that?)

4.  From within mg, the command
M-x rexx ^M 'rexx-insert "hello"' 
    gives error 47, arithmetic conversion error (trying to subtract insert
    from rexx); apparently rexx-insert not get correctly quoted, so
M-x rexx ^M ' 'rexx-insert "hello" ' '
    does nothing.  Absolutlely nothing.  Then
M-x rexx ^M ' "rexx-insert" "hello" ' 
    works!
 
5.  related to (4) above, what help would doing
C-u M-x rexx ...
    provide (ctrl-u is supposed to somehow quote the args, but unfortunately
    the mg docs could be clearer.

6.  finally, doing a 
M-x rexx-do-region
    on a region which includes the line
"address 'mg'"
    gives a code 3 return error (mg port locked).  I have a clue but
    would appreciate some more explanation.


Thanks!

p.s. Mike, you really ought to put in a short example on how to use
the commands name-last-kbd-macro and insert-kbd-macro ...it took me
quite a bit of trial and error to figure them out :-)

Thanks again!
