;
;	PRINT3 is THE file print utility for ZCPR2.  Installable by GENINS,
; PRINT3 provides a wide range of options for the user.  First, PRINT3 allows
; the user to employ wild cards and file name lists (lists of files separated
; by commas, like: file1,file2,file3,...).  Second, PRINT3 provides the
; following options:
;		E	Exact Mode
;				No heading appears, no line numbering,
;				no page numbering, tab expansion, form
;				feeds
;		F	File Name Toggle
;				The Heading Line can optionally contain
;				the name of the file
;		H@head@	Heading Text
;				The user may specify the text of the heading
;				to appear at the top of every page
;		I	Inspect Files
;				The user approves each file to be printed
;				before the printing process begins
;		L	Toggle Line Numbering
;				Each line may or may not begin with a line
;				number
;		M	Multiple Runs Toggle
;				The user may or may not be prompted to set
;				the Top of Form on his printer; Multiple Runs
;				ON means that he will not be prompted
;		N	Toggle Page Numbering
;				The numbering of each page is turned on or
;				off
;		Snnnn	Skip to Specified Page
;				Printing begins on the indicated page
;		T	Toggle Time Display
;				Time/Date information is optionally included
;				in the page header
;
