SCROLL MESSAGE EDITOR by Richard Karsmakers

Originally  published in ST NEWS Volume 1 Issue  6,  launched  on 
November 15th 1986.

It always is quite a race to finish the promised programs in  time 
for the launch of ST NEWS,  but once again it has turned out to be 
allright.  This program was written on Sunday,  November 9th, 1986 
(the  actual  rough  scrolling routine had been  finished  by  Jos 
Schilders  already about one or two months ago).  The  program  is 
added on the ST NEWS disk as a .LST file for GfA Basic.  It has to 
be loaded using the MERGE command of GfA Basic. After that, it can 
be  SAVEd to another disk using a normal SAVE (after which it  can 
be LOADed normally).  The reason why I made a .LST file of it, was 
that  we had big troubles with disk space on this time's  ST  NEWS 
disk  (we didn't want to make it double sided,  two  single  sided 
disks,  or maxiformatted).  A small user manual is included in the 
program  (in the default scrolling message).  This program is  not 
copy-righted,  nor are the 'message-files' that can be made of  it 
(these are files that can be MERGEd into your own program and that 
contain  a ready scrolling text -  typed in by  you.  They  simply 
have to be GOSUBed by you, and all is allright). But if you decide 
to  use this procedure in a (commercial) program of  your  own,  I 
would very much like to see a "thanks to" in it. You can also just 
give any amount of money on my giro account number 5060326 (t.n.v. 
Richard  Karsmakers,  Helmond,  The Netherlands) if you  like  the 
program!
The  procedure that the 'message file' option  creates,  can  very 
easily  be  adapted to your own needs (it can scroll  a  different 
line,  for  example).  It  can even be adapted to  work  on  color 
monitors;  if you want to use it in low resolution,  for  example. 
you'll  simply  have  to  devide  all  "PRINT  AT"  and  "GET/PUT" 
parameters by two - the large ones, anyway).
Try  to  run the Scroll Message Editor in  medium  resolution  and 
count  the colours (there are eight!).  I could also have used  16 
colours,  but that would make it all too messy.  How many  colours 
can maximally be used at once in medium resolution?....
