!* -*-TECO-*- !
!~FILENAME~:! !Alternate kbd macro pkg that allows dumping and restoring.!
KBDALT

!* The following up until Write Kbd Macro File is just KBDMAC !

!* 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,

!^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.!
