Joel West suggested the following method for creating C-style 
null-terminated resource strings:

The string can then be obtained using

	astrng = getresource("TEXT",id);

Many thanks to Joel for this *vast* improvement.  Except for one
thing (see below), this seems to solve the problem of getting C
strings into RMaker.  I will post a new version of SKEL incorporating
this idea in due course.

Before I do so, however, I'll mention a problem that Joel would not have
noticed with the strings he used, but which does exist with the strings
in SKEL.  That is, if the string includes periods (decimal points -
ASCII 2E) then the RMaker program as distributed with Megamax C will
not work properly.  It compiles a garbage string into the resource
fork.

I tried various obvious ways to get around this: \2E, \., \2\E, etc., 
none of which worked.  The only way I could figure to get around this
was to switch over to Hex (.H) mode in the middle of the string, drop in
the desired byte, then switch back to String (.S) mode, as follows:

.S
Here is the first part of the string
.H
2E
.S
  And here is the rest of it!\00

If anyone knows a better way to do this, I would like to incorporate
it in the new SKEL.  If no one can come up with a better idea within
the next week or so, I will post the version I have working now.  In
the meantime, you might want to experiment with this.

Can anyone at Apple address this?  The version of RMaker being used
is Andy Herzfeld's version dated 10/18/84.
