!* [toed.xkl.com]DXX:<EMACS>KBDMAC.EMACS.47,  5-Apr-96 18:18:50, Edit by ALDERSON!
!* Change naming convention for libraries from FOO.:EJ to FOO.ELIB on Tops-20!
!* <EMACS>KBDMAC.EMACS.46, 29-May-83 02:30:29, Edit by GERGELY!

!* A keyboard macro's data is represented using two ascii characters
 to describe each 9-bit character.  The first ascii character holds
 the top 2 bits of the 9-bit character, and the second ascii character
 holds the low 7 bits.  When the macro is run, pairs of characters are
 converted back into single 9-bit characters.
 Keyboard macros are encapsulated in TECO macros by putting the 37 chars
 "<Excl>temp<Excl>fm(m.m& Immediate Kbd Macro)" in front.
 This serves to make the TECO macro recognizable and to make
 it push the kbd macro when invoked.

 The keyboard macro call stack is a qvector in q..m.
 It has three slots for each call on the stack.
 The first slot contains the macro string.
   This string includes the call to & Immediate Kbd Macro.
 The second slot contains the index at which we are fetching from the string.
   The initial value of this slot is 37.
 The third slot contains the repeat count.!

A function is created with the name you specify,
which when invoked runs that keyboard macro.  (Return means give no name.)
Then, you are asked to give the command character to
put the macro on.  Type C-G if you don't want one.
Combinations with prefix characters such as Altmode and C-X may be used.

!^R Kbd Macro Query:! !^R Query and continue macro execution.
If called from a macro, reads a character:
Space continues execution.
Rubout terminates this repetition of the macro.
Altmode terminates all repetitions of the macro.
. terminates after the end of this repetition of the macro.
^R enters a recursive edit;  when you exit, you are asked again.
^L clears the screen and asks you again.
Anything else exits all macros and is reread as a command.

With an argument, we unconditionally enter a recursive editing level
and proceed with the macro when it is exited.  This is the same as
what we do with no argument if the user were to type ^R Space;
but it is done even when the macro is being defined.!

!Write Kbd Macro:! !C Write the keyboard macro(s) to a file.
	Writes one or more keyboard macros to a file.  The functions to
write are given as string arguments terminated by a null string
argument.  If there are no functions then you will be prompted for ONE
key to save.  If no errors in the preparation have occurred then you
will be asked for the filespec where to write the library (default
KMAC.ELIB).  You need only specify the file name.
	If the keyboard macros are bound to keys then those keys will
also be rebound upon the loading of the library, unless a numeric
argument is given to this function in which case just the function are
saved.
	To reload the library the user need only give the command
M-X Load Library<esc>libname, where libname is the name of the library
to load.
	A source file is written out and then deleted using the filename.EMACS
as the file spec.!
