MazeMaker BY Paul Skinner                                       
                                                                
(One of a suite of maze programs of mine). Can design a maze and
then choose a spot in it and enter into the maze to see  if  you
can find your way out.                                          
                                                                
Designer is 2D looking on top, and  entering  the  maze,  it  is
converted into 3D. Initial idea and some of the code I got from 
Format magazine.                                                
                                                                
----------------------------------------------------------------
                                                                
                                                                
SAM SCRATCH 3.21 (based on Supplement #12)                      
Modified by Simon N. Goodwin                                    
                                                                
SAM  SCRATCH 3.21  is a  slight tweak  from the  published  3.2,
it allows files up to 640 lines, so user will be  able  to  edit
all the text files  in  issue  12,  as  an  alternative  to  the
standard standard paged display. It is SLOWER at finding the end
of file, so 3.2 is still best for files up to 320 lines.        
                                                                
3.21 redraws the  screen  faster  (avoiding  output  of  blanks,
saving at best 1400   characters  of  output   per  page!),  and
tidies #0 afterblock operations (oops). The blink to red  screen
after EDIT is gone as I found it  distracting, and  the  re-draw
sequence is better now anyway. These are tiny  tweaks,  but  you
might as well have them.  I  don't  expect  to  see  this  on  a
Supplement disk as it is so similar to 3.2, but it may  come  in
useful if you need to edit a very long file.                    
                                                                
----------------------------------------------------------------
                                                                
CLIST by Simon N. Goodwin                                       
                                                                
{This is a simple but useful utility that  converts  a  Sambasic
program (or section of lines) into an ASCII CODE file  that  can
be loaded into SAM  SCRATCH or TASWORD!  It preserves LISTFORMAT
and wraps long lines automatically. To use it, just MERGE it  in
your BASIC, and enter CLIST a,b,c  where  a is the first line to
be converted  and b is  the last, and c  is  the  address  where
you want  the code to  be stored (default  65536, increase  this
if you need to convert a large program; maximum is 64K).        
----------------------------------------------------------------
                                                                
DIRECTORY VIEWER & SECTOR EDITOR by D.Kingsnorth                
                                                                
              The  two  programs  are  written  to work  with  a
standard SAM with 256k memory and use the  real  time  clock  as
found on the SAMBUS.                                            
                                                                
              The first I call a Directory Viewer. This loads in
a selected track and displays it on screen 256 bytes at a  time.
As the cursor is moved over the  various  positions  within  the
directory entry the function of that particular byte is shown at
the bottom of the screen. Pressing "N" puts the next half sector
on the screen or "T" allows the selection of another track. This
program is purely of a tutorial nature and is configured to work
with Dr.A.Wright's new Masterdos                                
                                                                
              The second program is a clone  of  the  first  but
this time there is no message at the bottom of the screen  other
than the cursor and save prompts. This  program  again  displays
256 bytes on screen but this time allows you to edit the  values
and save the new values to disk. Editing is achieved by  putting
the cursor over a value and typing in the  new  HEX  value.  The
cursor can then be moved to another position and  the  operation
repeated. When all the required changes have been made a push of
the return key brings up the prompt " commit the changes  Y/N  "
and if yes the changes are made  to  the  disk  sectors  in  the
selected track. This is  ideal  for  putting  line  0  in  basic
listings or taking them out !!!

PRINCE OF PERSIA TIPS by Bob Evans                              
                                                                
The final levels explained in detail, for those of you  who  are
still having trouble with this excellent game.                  
                                                                
Print them out, and keep them handy when you  are  playing,  and
the game is a doddle!!!!                                        
                                                                
----------------------------------------------------------------
                                                                
OVERLAYS by Les Phillips                                        
                                                                
Ever needed to use only certain keys on the keyboard,  but  kept
pressing the wrong ones in the heat of  the  moment?  Well, this
idea sent in by Les will cure all that by covering up  the  keys
that you don't need, leaving you to mark clearly  and  "get  at"
only the ones required for the program.                         
                                                                
Full explanation and instructions are given within the program.
