                         ++++++++++++++                         
                                                                
                                                                
SAMSCRATCH:-                                                    
    This is your free wordprocessor, so that you have no  excuse
for not writing to us.                                          
    It has not been changed in any way since last issue, but for
any  of  you  that  didn't  see  last  issue,  here  are  a  few
instructions for using it.                                      
    Typing any alpha-numeric character will print that character
on the screen. The cursor keys will  move  the  flashing  cursor
without erasing the text. You are shown 20 lines  of  text,  but
using the UP/DOWN cursors at the top and bottom of  the  screen,
will scroll the text in the relevant way. Pressing "ENTER"  will
take the cursor to the start of the next line, and "DELETE" will
of course delete a character.                                   
                                                                
                                                                
   At the bottom of the screen, you are  shown  which  line  and
column your cursor is on, and there  is  list  of  the  "F"  key
functions. Most of these are self explanatory.                  
   There is no word wrap, but if anyone feels  that  they  could
include one, I would be very interested to see it.              
     _______________________________________________________    
                                                                
CHARACTER DESIGNER:-                                            
                                                                
    This is a quite useful program that will allow you  to  work
on 2 character sets at a time.                                  
    The both  sets are displayed on the screen and you can  swap
between them at any time for designing purposes. A large grid at
the left of the screen shows you  an  enlarged  version  of  the
character that you are working on, and  the  grid  will  show  a
character from each set at the same time, so that 2  sets  could
be designed as a double height set to use in your own programs. 
   Use the  joystick  to  control  the  cursor,  and  "FIRE"  to
set/unset the pixels. The extra controls are shown at the bottom
of the screen and are as follows:-                              
                                                                
         G= GET A NEW CHARACTER FROM THE CURRENT SET            
         C=CHANGE TO THE OTHER SET TO WORK ON                   
         L=LOAD A CHARACTER SET INTO THE CURRENT SET            
         S=SAVE THE CURRENT SET                                 
         Q=QUIT BACK TO THE SUPPLEMENT                          
                                                                
     There is also an indication of which set you are working on
at the bottom right of the screen.                              
                                                                
This program was originally written for MGT, before  the  crash.
It was written specifically to allow the design of double height
character sets, that didn't look "blocky" as they do  using  the
CSIZE command. If you design all of one set as the tops  of  the
characters, and all the other set as the matching bottoms, it is
a very easy task in BASIC to PRINT these one above the other  to
give 16x8 text in any design you like.                          
There is a PROCedure in the program section of this  disc,  that
allows you to use the new sets within your own programs.

FLASHPATCH                                                      
A very simple program, which takes a screen$                    
done with FLASH, and resaves it so that it loads  as  a  screen$
without the flashing palette that you sometimes get.            
    ________________________________________________________    
                                                                
SAMCAD:- by Peter Wood                                          
                                                                
     An ingenious program which allows you to  design  CAD  type
screens and save them off for your own use. The program contains
the facilities to redefine the character set, LOAD and SAVE sets
or complete screens and has a very useful HELP facility.        
    There are 2 demo screens contained on this disc  along  with
the 2 character sets that go with them.                         
    From within the program LOAD:- "builtset" as the characters 
                                   "cadhouse" as the screen     
                                                                
                          or LOAD:-"electset" as the characters 
                                   "cadcir" as the screen       
                                                                
This program could be used to design any type of line drawing   
such as floor plans, garden layouts etc. Although very simple in
concept, it is only limited by the users imagination in the uses
it could be put to.

NEW TASWORD BASIC:- by Dave Kingsnorth  (added to by B.Mumford) 
                                                                
   This is a modified BASIC for you to put on your  Tasword  Sam
disc. It contains the ROM fix for version 3  ROM's  as  well  as
giving you the option to DIR the disc before a LOAD or SAVE.    
There is also an ERASE facility to erase your Tasword files from
within Tasword, and the main menu  now  contains  a  line  which
tells you the current drive, and gives the  option  of  changing
drives to LOAD/SAVE/ERASE from.                                 
Instructions for tranfering it are given in the program.        
Also included on this disc is a program called "PRINT_SET".  Add
this to your Tasword disc, and if you use the "Return to  BASIC"
option in Tasword, you will be given the  option  of  loading  a
printer setting routine.

SPECSCREEN by S. Wilson                                         
A small, but useful utility, that takes MODE 1 Sam screen$,  and
records them onto tape, so that the Spectrum can read them.     
 __________________________________________________________     
TASREADER:- by D.Tonks                                          
                                                                
    A small program that lets you view and print out any Tasword
file, without having to load Tasword.                           
Full instructions on how to SAVE it as a stand alone program for
your own use, are given in the program.                         
                                                                
_____________________________________________________________   
                                                                
GRAPHS by Steve Monk                                            
                                                                
A complete program for showing in  graph  form,  most  types  of
tables. E.G electricity bills over the year. There are  examples
contained within the program,  so  you  can  see  how  it  works
straight away. A very useful and well written program.

DISC/TAPE HEADER READER by S.Wilson                             
                                                                
A nice little utility,  that  will  read  either  tape  or  disc
header information, and display it,  either  to  the  screen  or
printer.                                                        
                                                                
  _____________________________________________________________ 
                                                                
                                                                
                                                                
SOUND HELP by S.Wilson                                          
                                                                
This must be the most information  every  put  together  in  one
article, explaining the Sam sound chip. Everything that you ever
wondered about the chip is in here. A  must  for  the  musically
minded of you out there.                                        
                                                                
This program also appeared in OUTLET

LAZER MAZE by D.Tonks                                           
                                                                
Another one of those "BRAIN GAMES", based on  the  old  Spectrum
"BLACK BOX". You have to find 8 power disrupters  within  a  7x7
grid, by shining your lazer through the grid.                   
It is in mode 4, and  uses  the  Sams  extra  colour  etc.  Full
instructions are included in the game.                          
________________________________________________________________
                                                                
BIGPRINT by D.TONKS                                             
                                                                
This is a DEFined PROCedure, that is used in conjuntion with the
CHARACTER DESIGNER in this issue. It can be merged onto your own
programs, and used with a predefined character  set,  will  give
8x16 characters, which are smoother than you would get with  the
normal CSIZE command.                                           
There are instructions on it's use within the program,  and  the
option to save just the PROCedure, for your own use.            
                                                                
                                                                
COLOUR CLIP  (PD)                                               
                                                                
This is a different sort of clip art. What it is, is  a  SCREEN$
of full colour characters, most of which are  shown  in  several
stages of animation. These can be GRABbed and used  within  your
own programs, giving them a very professional appearance.       
We shall be having one of these SCREEN$ in nearly every issue of
the mag, each with  a  different  theme.  If  you  have  created
anything similar then please send it in and I will use it in one
of the issues.                                                  
The 2 flying birds on the instruction screen were taken off this
months SCREEN$, to show you the general idea.                   
                                                                
________________________________________________________________
                                                                
                                                                
                                                                
                                                                
                                                                
                                                                
OPUS TO SAM CODE CONVERTER by G.BATES                           
                                                                
If you own a SPectrum and Opus disc  drive,  then  this  program
will prove invaluable. Originally written to read Tasword  files
straight off Opus discs, and convert them to Sam disc,  it  will
actually read any CODE  file.  I  found  this  most  useful  for
Spectrum SCREEN$, which after saving onto Sam  disc,  will  load
straight into FLASH in MODE 1.                                  
Please read Gerry's letter in this issue,  which  contains  some
important info on the programs use.                             
________________________________________________________________
                                                                
COLUMNISER by D.Hall                                            
                                                                
If you've ever wanted your printouts to be  layed  out  in  neat
columns, like you see in newspapers, then this  program  is  for
you. It will take Tasword files and split them up into 1,  2,  3
or 4 columns and resave them  for  your  use.  The  program  has
several useful help pages, and is very easy to use. This is only
the first of part of a much bigger project by Dave Hall.        
ODDS and ENDS by various people                                 
                                                                
This is a collection of small demos, screen$  etc.  which  don't
really warrant a place of their own on the program menu.        
I've put them all together on their own little sub-menu with the
option to return to the main menu, if you wish.                 
                                                                
All are in BASIC, and can be broken and LISTED to see  how  they
were done.                                                      
This may become a regular feature, so send  in  those  routines,
I'll find a place for them in  the  Supplement,  no  matter  how
small they are.                                                 
                                                                
                    ### # # ###   ### ### ##
