0 ( Greetings from Team Forth )
1 24 LIST = crib sheet >
2 Team Forth welcomes you to the
3 world of Atari fig-Forth. We are
4 trying to make FORTH easy for
5 you to learn and use. Since we
6 are learning too, we would be
7 pleased to get any feed back you
8 may have on this version of fig-
9 FORTH, and the included documen-
A tation. Please send any comments
B to Team Atari, 4029 Payne Ave.,
C San Jose, Ca., 95117 or leave
D E-mail on Compuserve for ~[70525,
E 434] We'll try to answer all
F correspondence. (TYPE LL) Rev.H+
10 This disk is an attempt to write
11 a self-tutorial on using this
12 version of fig-FORTH. Just read
13 the text and try the examples by
14 placing the cursor on the line
15 with the example and pressing
16 the <RETURN> key. Have fun.
17 NOTE 0 LIST is a catalogue.
18 Let's try out a couple of words.
19 ( UPPER LIST & LOWER LIST )
1A
1B Ok To begin, type in the lower
1C screen area. First type UL <RE
1D TURN> then to return here type
1E LL <RETURN>, then to go to the
1F next screen by pressing <N>
SCR # 21
0 ( PREVIOUS, NEXT, TOGGLE )
1 Now type P and then use the T
2 command to get back here. OK,
3 N = next, P = previous and T =
4 toggle; FORTH stores the last
5 two screens you LOADed or LISTed
6 or EDITed in two buffers which
7 you can toggle by using <T>.
8 This is especially handy to
9 compare screens from different
A areas of a disk, or from two
B different disks.
C
D The next handy-dandy command to
E learn is the INDEX word.
F (TYPE LL TO CONT.)
10 INDEX is the word you use to see
11 what is on one of your FORTH
12 source disks. It shows you the
13 first line of each screen on the
14 disk. ( perhaps I should mention
15 that FORTH organizes the disk in
16 screens, the units you have been
17 looking at, i.e. that which will
18 fill up a TV screen. A good rule
19 to follow is to make the first
1A line of any screen you write a
1B short description of what is on
1C the screen. Then when you use
1D INDEX you get a quick list of
1E the contents. By printing this
1F you have a nice (TYPE N)
SCR # 22
0 ( ."/LPINDEX/SHOWLP/LPOPEN/ )
1 listing of the contents of the
2 disk. To try this out type in
3 the following line down below:
4 0 GR. 0 4D INDEX or you might
5 try useing <SHIFT> <CLEAR> and
6 then typing 0 4D INDEX.
7 ( Must be in caps )
8 <."> is a FORTH word pronounced
9 DOT QUOTE that works with <">
A pronounced QUOTE to print the
B text included between them.
C Make a note...
D TO RETURN HERE TYPE 12 UE
E (for page 12, uppper edit)
F then type LL to continue.
10 Now to print the Index, you need
11 to get your printer all ready,
12 type LPOPEN, and then type-
13 0 4D LPINDEX. This will print it
14 out. To print any single screen
15 you type xx LISTLP (xx being the
16 screen number). Two screens may
17 be shown side by side on a page
18 from the printer by typing -
19 xx SHOWLP. This will print scrn.
1A xx and the next screen after xx.

SCR # 23
0 ( BACKUP/CSECTS/WARN/GS/WS/N/+ )
1 By now you may have wondered how
2 to copy this disk. You can't do
3 it using standard DOS as there
4 is no Directory on a FORTH disk.
5 You can use 'SUPERDUP', ARCHIVE,
6 or any other sector copier.
7 The word SYS will load several
8 useful words like FORMAT and
9 MAKEBOOT. MAKEBOOT makes a boot-
A able disk with all the words you
B have defined included. SYS
C will load a menu screen giving
D instructions. NOTE: DO NOT MOVE
E any of the screens 1 through B
F and F !!! (type LL)
10 To turn on the english error
11 message system, type WARNON. To
12 turn them off and get only #
13 msgs type WARNOFF.
14
15 The options available now for
16 screen color are GS=green scrn,
17 WS=white screen, NS=normal scrn,
18 BS=black screen. Give them a try
19 and see which ones you like.
1A
1B Now try HX, DX. The border color
1C will change to remind you which
1D number base you are in. NOTE
1E HEX & DEC or DECIMAL are good
1F too. (type N to cont.)
SCR # 24
0 ( GENERAL INFO. )
1 Now that we have some basic
2 tools with which to find our
3 way around the disk, a little
4 general information on how the
5 goodies are stored here. This
6 disk contains most of the words
7 of this version of fig-FORTH in
8 the compiled form, i.e. they are
9 LOADed and ready to use. You got
A the list of words available to
B you if you printed out the
C VLIST. The second disk in this
D package contains a very small #
E of words in compiled form and
F (type LL to cont.)
10 the rest are on source screens.
11 This allows you to keep your
12 kernel (the compiled words) of
13 FORTH as small as possible, thus
14 saving as much memory space in
15 RAM as possible. The more words
16 compiled in RAM the less room
17 for you to work with in your own
18 applications. In order to add a
19 section of words to the kernel
1A just LOAD the screen they are on
1B by typing xx LOAD. (xx is the
1C screen number). xx L& turns of
1D the screen for faster compila-
1E tion, but use it only on tested
1F screens. (type N to cont.)
SCR # 25
0 ( LIST/L./DOIT/WIPE )
1 The format you have been using
2 so far is the EDITOR format.
3 You can look at screens in two
4 different formats. By typing L#
5 you will get line numbers on the
6 editing screen to facilitate use
7 of line edit commands. If you
8 want to get rid of them later
9 just type NL# and they will go.
A
B The other major format for look-
C ing at screens is the LIST or L.
D format. Type xx L. to see this
E one.
F (type LL to cont.)
10 In the LIST format you have to
11 use the <CTRL><1> key to stop
12 and start the scrolling of the
13 screen.
14
15 The next screen is blank so you
16 can try some screen editing.
17 Type N to go there and then type
18 on the screen. When done use the
19 cursor arrow keys to move down
1A to the line with "DOIT" on it &
1B press the <RETURN> key. Then
1C type FH or FLUSH to save it to
1D the disk. To erase it type
1E 16 WIPE, or W while in the
1F editor (TYPE 17 UE TO SKIP THAT)

2 REV.G has a number of bug fixes
3 for REV.A OS. It also intercepts
4 the DOSINI vector during BOOT,
5 and at WARMSTART (RESET). This
6 makes it possible to set screen
7 colors and margins at boot up
8 and reset.
9 Simply set your margins and
A screen colors before calling SYS
B Select STACKON or STACKOFF. Then
C command SETSYS, and MAKEBOOT.
D Your new disk will now boot in
E your colors, and have your mar-
F gins. <LL>
10 You can also hook in an ML SUB-
11 ROUT.at this time. It must have
12 been defined prior calling SYS.
13 After calling SYS, command
14 HOOK word (<your assembler word)
15 UNHOOK reverses the process, if
16 you think you made a mistake.
17 NOTE: Your word is called as
18 a machine subroutine, and must
19 end with RTS,.
1A The screen editor now has a
1B KEYBOARD intercept, so you can
1C not accidentally hit CR while
1D editing the upper screen. To
1E override CR on the upper portion
1F ( while editing) hit CTRL CR (N)
SCR # 28
0 ( scr# 18 REV.G contd. ) ;S
1 UNLINK (DEFAULT) disconnects
2 Dr2 (810 only) from PHYSOFF,
3 your second disk normally does
4 not contain the BOOT, e.g. SCR
5 # 0 starts at sector 1. LINK
6 reverses UNLINK.
7 Note that a lot of screens have
8 been changed from the previous
9 REV., so full compilation
A requires staying with one group
B of source screens. The enhanced
C SYS commands should not be used
D with KERNELS of previous REV.s.
E CHECK SCR#'s $24 for EDIT comnds

3 0VP = P/0 vert. position
4 0HP = P/0 hor. position
5 0VPOLD = P/0 old vert. position
6 GETPS = get player shape & place

A of player in HEX. <setcolor colo
B r * 16 + luminance> The first
C no. in front of SIZE! is the P/M
D width no., 2nd is no. of P/M.
E The no.s for GETPS in SPLAY are:
F 1. the no. of screen holding P/M
10 2. the # of bytes into the scrn.
11 where the Player data starts.
12 3. the # of bytes of player data
13 4. the hor. pos. to show player
14
15 You must be careful to place the
16 data correctly on the data scrn.
17 Count in carefully and enter the
18 data in characters. This is done
19 by using BDUMP to enter the HEX
1A numbers into RAM buffer position

0 ( BDUMP/ EXAMPLE )
1 To put these numbers onto the

3 Atari control keys in the table,
4 you use the BDUMP word. In this
5 case it works like this. You
6 type the following: 1C BLOCK
7 DUP 2A + BDUMP This gives you
8 the top 2A character positions
9 of screen 1C displayed on the
A monitor. You then count in the
B number of spaces you want the
C data to be and enter it on the
D screen using the cursor and
E pressing <RETURN> on the same
F line. (Type LL to cont. )

6 stick 0. You will notice that
7 the shape "hides" behind the

A Later you can draw some play-
B field stuff and experiment with

10 The graphics commands in this
11 FORTH for the Atari are very
12 like those you use in BASIc
13 except that as you have noted
14 here the numbers come first not
15 after the commands.
16
17 x C. = COLOR x
18 x GR. = GRAPHICS x
19 x y PL. = PLOT x y
1A x y DR. = DRAWTO x y
1B similarly POS. is POSITION, SE =

14 After looking at this one play
15 around a little. It will take
16 some work to make this display
17 four players at the same time,
18 but its fun to try. You may want
19 to go back and redefine some of
1A the words to expect the player
1B number on the stack to tell them
1C which player to work on, or you
1D can just define a word for each

0 ( STACK DISPLAY )
1 One of the nice features of this
2 system is the stack display. To
3 use it just type STACKON. Then
4 type a few numbers and press
5 <RETURN>. You will see them show
6 on the stack display at the top
7 of your monitor screen. To turn
8 it off when unwanted STACKOFF.
9 You will find the STACK display
A very useful to you as you start
B defining your own words as you
C can go through each step in the
D word singly and watch what it
E does to the stack. The stack is
F the single most difficult (LL)
10 thing for most begiinning FORTH
11 nuts to understand, and this
12 display is used by even the
13 experienced programmers I know.
14
15 Put some numbers on the stack
16 and try some of the Math words
17 like + and /, and *. Use SWAP,
18 and ROT, and . and DROP, etc.
19 and observe their stack effects.

1 Now we come to one of the most
2 useful and powerful words in the
3 vocabulary of this FORTH version
4 the decompiler word. To use it
5 just type DC xxxx, with xxxx the
6 word you want decompiled or
7 taken apart. This word works on
8 even the primitive words in the
9 fig-FORTH kernel. Try a few of
A the simple words first, like
B GS, or NS. When you do you will
C find that the numbers above 0,1,
D and 2 all have LIT after them.
E The first three are used so much
F that they are FORTH words. (LL)
10 ( screen 21 )
11 The LIT tells FORTH that the
12 They are to be taken as literal
13 values. To give you an idea how
14 this works try typing in this
15 definition and then DC AS.

1 This should give you enough to
2 think about for quite a while if
3 you are new to FORTH. We haven't
4 tried to make you a programmer,
5 but just to introduce you to the
6 features of this version of the
7 language and help you over a few
8 of the initial rough spots.
9
A There are several good books for
B new people in FORTH. The one I
C personally found most helpful
D was DISCOVER FORTH published by
E McGraw Hill. The best next book
F and probably the best (LL)
10 if you can only afford to buy
11 one is STARTING FORTH by Leo
12 Brodie, and published by FORTH
13 Inc.
14
15 I wish you the best of luck and
16 hope that you will keep us up to
17 date on your extensions to this
18 language. We will try to act as
19 a clearing house for ATARI FORTH
1A people. AS we come up with more
1B features we will add them to the
1C package. we will try to upload
1D the new stuff onto Compuserve
1E ACCESS area so that you can get

SCR # 33
0 ( CONCLUSION )
1 updates without a lot of mailing
2 disks and paying postage. To
3 this end I suggest that you keep
4 the original source disk without
5 change so that you can recompile
6 your working kernel as you get
7 updates. If someone writes us
8 a terminal prgram written in
9 Atari FORTH we will make it
A available immediately so that we
B can all communicate FORTH stuff
C more easily, without typing in
D the screens on the keyboard.
