The MLR MACRO Language, V2.3


The MLR MACRO Language is a set of macros which implement structured
programming in MACRO-32. 

These include:

	MODULE
	PROCEDURE
	BEGIN
	IF-THEN-ELSEIF-ELSE
	CASE
	DO
	FOR
	LOOP
	WHILE
	REPEAT-UNTIL
	REPEAT-FOREVER
	BREAK
	CONTINUE
	GOTO
	STRUCT
	UNION
	MAP
	DESCRIPTOR_S
	DESCRIPTOR_D
	and others

Documentation is included on tape in VAX Standard Runoff format.

This version of MLR replaces the Spring 1986 [VAX86A.ELDR] VAX SIG tape
submission.

This updated version of MLR also replaces "VAX-186, The MLR MACRO Language,
Version: Spring 1986" (V1.0) in the DECUS Program Library. 


There are four files on this tape:

	README.1ST	(this file)
	MLR.HISTORY	(short history of MLR development)
	SOURCE.BCK	(source macros and libraries)
	RUNOFF.BCK	(runoff documentation)
