	TITLE	SPDSPL - PostScript printer spooler

COMMENT \
	This program augments the standard LPTSPL as the lineprinter
	spooler. It features a number of functions in addition to the
	normal ones. It handles any number of devices (streams) up to
	maximum NPRINT which may be changed. Each stream executes in its
	own subfork. Also, by specifying TCP instead of a TTY as the
	printing devices PLPTx:, files will be spooled over the
	net using TCP. 

	Physical LPTs and spooling to mag tape are NOT supported.

	The Forms parameter file SYS:LPFORM.TXT also has a different
	format as compared to LPFORM.INI, see below.

	This stuff was written in the Fall of 1984 by
	Bjorn Lindskog, Computer Science Lab, U of W, Seattle

	Well, this sort of came to me by a roundabout route, and I won't
	claim a lot of responsibility except to say that it seems to work
	for me. 

	I've added compatibility for PostScript printers and for named units
	ala Columbia.

;Macros used in inferiors's code

;The TXT macro is a poor man's implementation of the $TEXT macro. It is
;used by the inferiors since the original $TEXT in GLXLIB uses
;non reentrant code.
;This one uses the reentrant routines TXT.xx for the different functions.
;It takes three arguments: TXT(type,address,string)
;Type indicates whether address is the address of routine that outputs the
;char in C or the address of buffer. <> 0 is buffer.
;The string accepted has the following format:
;^<function character><argument>^<function character><argument>...^
;See macro TFUNC for a listing of the functions.
;The first function of the string is defaulted to ^! i.e. no function.
;Note that S1 and S2 are not preserved and cannot be referenced in the
;string.

;Macros used to build the argument strings
;Use CLSTR to init, APPSTR(TXT) to add TXT at the end and
;EXPSTR to get the string back.

;Macro used to build the definitions. Two macros TFBx and TFAx are
;created for each function character. TFBX is expanded when the 
;function character is detected. It is used to init the argument
;string if necessary. TFAx is expanded when the 
;argument has been collected i.e. at next ^ or at end of input.
