%  (3) Finegray Rubbergrid
% . . . . . .

% Creates fine gray grids without dropouts or rattiness.
% The code shown is device specific for 300 dpi printers.

% To create a grid, use  -hpos- -vpos- -gridsize- setgrid
% Until restored, all further images will be "locked" to
% the grid and will expand and contract with it. Note that
% optimum linewidths and font sizes will usually be much
% less than 1.0 after locking.

% To show a grid, use -#hlines- -#vlines- showgrid.

% The seegrid command displays the grid when true.
% The fat5 command emphasizes every fifth line when true.
% the fatter10 command emphasizes every tenth line when true.

% Here are the graphing grays. For most users most of the time,
% select ggray4 or ggray5 as your default ggray.

% GONZOJST.PTL is a series of utilities that allow ultra high quality
% text justification from within a word processor or editor environment.
% The routines are fast, fully programmable, use minimum length files, and
% use little VM. They are purposely not WYSIWYG for maximum flexibility,
% speed, and total device independence. Advanced features include auto drop
% caps, hanging punctuation, individual kerning, lastline stretch, simple
% textdumper, callout modes, macros, overstrike, and much more. The routines 
% be used WITHOUT control characters. They can emulate nearly anything.
% An internal compiler is included for extremely fast rerun times.

% Full use instructions appear in the companion file GONZO13A.TXT.
% Also see the internal notes and comments below.

% This default text dumper template is useful for "just dump the text"
% applications. The | and \ characters are handled as ordinary text in
% this example. The only gonzo commands used are for the carriage return
% and the linefeed. A "double escape" | | exits you.

% This template is also useful to list your gonzo programs while PRINTING
% (rather than executing) all internal gonzo commands. (!!!)

% Note that any template MUST have an internal proc named templatestartup
% and that your template MUST NOT call gonzofont before run time.
