.b 3
This macro sets up the environment for an interal module.
.b
If ^&psect-name\& is specified, then the string "_local" will be appended to
the ^&psect-name\& and will be the .PSECT name, otherwise, the name of the
module appended to the string "_local" will be the .PSECT name. 
.b
If _<^&argument-list\&_> is specified, each argument in the list will be
appended to the module name and each resultant string is used in a constant
assignment, assigning each with it's offset value from AP.  The string ".narg"
appended to the module name is always assigned the value of 0 and represents
the number of arguments passed to this module.
.b
If no arguments are specified in _<^&argument-list\&_>, then _<_> must be
specified as a place holder for the _<^&argument-list\&_>.
.b
If _<^&register-list\&_> is not specified, _<_> is assumed.
.b
The CONST macro and the VAR macro generate no code and are optional and can be
specified as often as required for documentation purposes. 
.b
The BEGIN macro separates the data portion of a module from the code portion.
The BEGIN macro must be specified.
.b
The EXIT macro will generate a $EXIT__S r0 instruction.  If value is specified,
the value will be moved to r0 before the $EXIT__S intruction is generated.  If
^&type\& is not specified, L is assumed. 
.b
The RETURN macro will generated a RET instruction.
.b
The END macro is used to end the module. For every MODULE macro specified, an
END macro must also be specified. If this is the last module in the assembly,
an .END instruction can be specified instead of the END macro. 
.b
For example:
.b
.lt
	module name
	var
		save:		.blkw 1
	begin
		movl	r0,save

		statements-1

		movl	save,r0
		return
	end
