;    PRINT is THE file print utility for ZCPR3.  Installable by Z3INS,
; PRINT provides a wide range of options for the user.  First, PRINT allows
; the user to employ wild cards and file name lists (lists of files separated
; by commas, like: file1,file2,file3,...).  Second, PRINT 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
;        Onn    Offset Each Line
;                Move each line in the indicated number of
;                characters from the left
;        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
