			Abstract

	This macro PRE-PROCESSOR is provided to allow the user to write code
that can easily modified for multiple environments, conditions, etc  simply by
changing parameters at the beginning of his code. 
	Capabilities included are: macros, conditional assembly, loops,
automatic label generation, including other files, macro directive nesting,
etc. 


	A program written for the macro PRE-PROCESSOR consists of directive
declarations and substitution operations. directives are to be on lines by
themselves (no source code). Substitution operators can be almost anywhere. 
	Two output files can be generated, a list file(.LIS) and a resulting
source file (.SRC) .
	The following is a summary of directives, substitution operators and
predefined variables:

*COMMENT
*ENDCOMMENT

*MACRO(name)
*ENDMACRO

or

*ELSEIF(expression)
*ELSE
*ENDIF

*SET(var=value/string/logical expression)
*REPLACE(var=value/string/logical expression)
*DEFAULT(var=value/string/logical expression)
*DELETE(var)
*REMOVE(var)

*DO(idx=start expression,end expression[,increment expression])
*ENDDO

*LIST(name)
