; Batch File:  NZSUB.SUB
; Author:      Joe Wright
; Date:        8 November 1988

; This file demonstrates NZSUB's ability to handle 'formatted'
; input files.  The programmer will note the similarity to
; annotated assembly source files.

; This file will also serve as the documentation of NZSUB's
; features and function.

; As these lines suggest, any line that begins with a ; is considered
; a full-line comment and is ignored.

; The ; character is usually the command separator for a Z3
; multiple command line.  It is therefore a 'normal' character
; unless it is the first one and may appear freely in the command
; line preceded by anything except a space.

; Blank lines are ignored in any case.

» Ok¬ dowî tï business.  The main point of all this is to relax
; some of the constraints on command line formatting so that
; a batch file becomes more legible and therefore maintainable.

; Command lines may be indented with any combination of spaces
; and tabs.  A tab within a command line will be converted to
; a space.  Spaces between the last command character and the
; in-line comment ';' or ';;' will be removed and the comment
; ignored.  The ';;' ZEX form may be used but is unnecessary
; if the ';' is preceded by at least one space (or tab).
