myForth supports most of the ANSI forth core words
with the 
INCLUDE core
command.

In addition, I have added a basic line graphics mode 
with the 
INCLUDE GR
command.

Afterwhich, you may use line graphics draw mode 
with the 
TRUE grEnabled
command.

Your canvas size is returned with the 
grSize? .s 
command.

800 560 <sp ok


You may change the colors and draw a line with this example 
FG@  RED FG!  100 100 200 200 drawline  FG!


Basic ANSI cursor control is available in text and graphics modes

: ANSI-ESC 27 EMIT 91 EMIT ; 
: AT-XY ANSI-ESC  0 <#> TYPE  ." ;"  0 <#> TYPE ." f" ; 
: PAGE  ANSI-ESC ." 2J" ; 
: HOME  ANSI-ESC ." H" ( or 'f' ) ; 
: CUR-UP   ANSI-ESC  0 <#> TYPE  ." A" ; 
: CUR-DOWN ANSI-ESC  0 <#> TYPE  ." B" ; 
: CUR-RIGHT ANSI-ESC  0 <#> TYPE  ." C" ; 
: CUR-LEFT  ANSI-ESC  0 <#> TYPE  ." D" ; 
: CLEAR-EOL ANSI-ESC ." K" ; ">


You may create myForth website applets ( forthlets ;) ) 
( for non-commercial use ) using either the 
INCLUDE command ( Forth source converted into Applet PARMS 
will need to substitute quotes,   " into '' , read html source FUDGE  )
or using the FROM-URL command.
( FROM-URL can be used inside INCLUDE command for quick loading tests )

FROM-URL can load a text file from your website.
For example

INCLUDE core
INCLUDE http://mywebpage.netscape.com/mawcowboy/count.4th
T1

works.

Interpretive [IF] [ELSE] [THEN] [ENDIF] [DEFINED] [UNDEFINED] and included
with the 
INCLUDE interpif
command.

v.45
added ability to include forth source files within jar resource files
  ( for example, to add conditional compilation directives, 
    use 'INCLUDE interpif' , interpif is a jar resource file )
added nested INCLUDE ( four levels deep),
  ( a resource file, an Applet parameter list or URL maybe specified )
  ( if you use myForth as a local application ( vmMain) then 
    local files maybe included with 'INCLUDE file:c:filename.f' )
added various performance enhancements 
  ( performance is, generally, better with NS48, IE55 and jdk 1.1.8,
    than jdk 1.4.1 )

If you use the Applet interface locally, you will need to modify 
the html files for you directory structure.
