!* [toed.xkl.com]DXX:<EMACS>FIXLIB.EMACS.210, 5-Apr-96 18:17:04, Edit by ALDERSON!
!* Change naming convention for libraries from FOO.:EJ to FOO.ELIB on Tops-20!
!* This file requires EMACS;IVORY -- not EMACS;PURIFY.!
!*
* This library contains functions for aiding the writing, editing, and
* debugging of EMACS functions, generally assuming the use of the IVORY (not
* PURIFY) library for library generation. Note that this library is
* basically UNSUPPORTED -- it is primarily used by ECC, EAK, FJW. We do not
* have time to make this a maintained package, but anyone can use it at
* their own risk.
* Unless someone objects strenuously, this library will assume TMACS is
* loaded.
*!
!* Recent modifications:
* 9-Sep-82 ECC 208 Add Remove (TEST) Suffix. Extend EMACS Function
Occur to filter on names too. Add Goto Function and
Bound variable. Fix yanker to change excls to ^^s.

!Remove (TEST) Suffix:! !C Trims an MM-variable to proper name part.
String argument is command name. If null, reads it with completion.
After a Test Load has left a (TEST) suffix, completion will be ambiguous.
Using this command will change the MM-variable from, say, MM Foo (TEST)
to just MM Foo.
Note that this means that various commands won't be able to recognize this
MM-variable as a test function any more.!

!^R Goto Teco Function:! !^R Function name taken from left of point.
Picks up teco function name to left of point, using ^R Goto Previous M.M.

bounds are set.!

!EMACS Function Occur:! !C List functions in source file containing a string.
Buffer should be an EMACS source file.
The first string argument is a search string: the functions whose source
contains that string are listed. Null string means don't show lines,
just the function names.
The second string argument is a search string that further filters those
matching functions: only those functions whose names match this string
are listed.
No NUMARG means do over whole file from top.

!Backtrace:! !C View the frames on the macro-pdl. Indents compressed code.
Displays one invoked macro, copied into a buffer,
with point at the PC. Then reads a command character:
Linefeed or D goes down the stack (to earlier invocations),
^ or U goes up to more recent invocations,
^R calls ^R on what you see, ^L clears the screen,
B calls ^R on the buffer that was being edited,
A shows the macros's arguments,
I indents the code (binding Indent Teco Object),
V displays a q-register's contents,
runs a minibuffer, X runs MM command, Q exits.
