*** STOS + Fun School II updaters ***

     The three PRG files on this disc allow you to update a
STOS Language, STOS Compiler and ST Fun School II disc so that 
they will be compatible with the new STE machines.

               *** STOS Language disc Updater ***

     STOS Basic has been updated twice since its original 
release. Version 2.3 was first, then came 2.4. It was necessary 
to release 2.4 with the STOS Compiler because we introduced a 
faster floating point maths routine which would only work with 
versions of STOS greater than V2.3.

     At this point we did not change the masters for STOS Basic 
because we wanted to offer the original double precision floating 
point routines to all STOS users. With the advent of the new 
Atari STE machine we have had to update STOS again. The STE 
proved to be totally incompatible with STOS so alterations were 
made and version 2.5 was born.

     You must therefore be aware of the changes from 2.3 upto 
2.5, most alterations concern the fixing of obscure bugs that 
users have reported to us. The main change is the new floating 
point routine: Version 2.3 used the latest IEEE standard for its 
floating point numbers. This allowed your program to use numbers 
between -1.797692 E+308 and +1.797693 E+307. These numbers were 
accurate to 16 decimal places. However it was quickly discovered 
that few users really needed this level of accuracy, especially 
in a game environment. We therefore opted for a faster single 
precision system, this allows a floating point number to range 
between 1E-14 to 1E+15 (7 decimal places).

     If you get hold of a Basic listing that was written on V2.3 
and it uses the old floating point routines, you will have to 
update it first using the CONVERT.BAS file. One of the existing 
files (COMPACT.ACB) will need updating before it can be used with 
the new STOS. CONVERT.BAS can be found on this updater disc.

     One last thing to note: If you buy the Compiler after 
updating to 2.5, remember not to update your language disc unless 
it is a version greater than 2.5.

                  *** STOS Compiler Updater ***

     The Compiler also has to be updated to the latest version. 
Bugs reported by users have all been fixed to give a more 
reliable product.
     To update simply double click on COMPNEW.PRG and follow the 
on screen prompts.

                 *** Fun School II Updater ****

     Fun School II was written in STOS Basic and thus needs the 
same sort of update as STOS.

     The updating procedure is very simple and only requires you 
to update disc 1 of Fun School II. All age groups can be updated 
using the same updater.
