WORKSPACE MANAGEMENT
====================

PROCEDURE DEFINITION
--------------------

TO procname :input1 :input2 ...				(special form)

	command.  Prepares Logo to accept a procedure definition.  The
	procedure will be named "procname" and there must not already
	be a procedure by that name.  The inputs will be called "input1"
	etc.  Any number of inputs are allowed, including none.  Names
	of procedures and inputs are case-insensitive.

	Unlike every other Logo procedure, TO takes as its inputs the
	actual words typed in the instruction line, as if they were
	all quoted, rather than the results of evaluating expressions
	to provide the inputs.  (That's what "special form" means.)

	Logo responds to the TO command by entering procedure definition
	mode.  The prompt character changes from "?" to ">" and whatever
	instructions you type become part of the definition until you
	type a line containing only the word END.



WORKSPACE CONTROL
-----------------

SAVE filename

	command.  Saves the definitions of all unburied procedures,
	variables, and property lists in the named file.

LOAD filename

	command.  Reads instructions from the named file and executes
	them.  The file can include procedure definitions with TO, and
	these are accepted even if a procedure by the same name already
	exists.  If the file assigns a list value to a variable named
	STARTUP, then that list is run as an instructionlist after the
	file is loaded.
