- STOS + Fun School II updaters 1/09/90
- ----------------------------------------
-
- 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 latest STE machines which offer TOS 1.62 in ROM.
-
- The original STE machines had TOS 1.6 on ROM. This new TOS 1.62 breed
- of STE seems to be restricted in its circulation. We had great
- difficulty locating such a machine and to our knowledge it has yet to
- hit the UK in any large numbers.
-
- Even if you don't own such a machine, it is still very important for
- you to update. Otherwise all the programs you write and Compile in
- STOS just won't work on TOS 1.62 machines.
-
-
- STOS Language disc Updater
- ----------------------------
-
- STOS Basic has been updated three times since its original release.
- Version 2.3 was first, then, following as an update with the STOS
- Compiler, came 2.4. It was necessary to release 2.4 with the 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 had
- to update STOS again. The STE proved to be totally incompatible with
- STOS so alterations were made and version 2.5 was born. About a year
- later Atari did it again! - another Atari STE, this time with TOS 1.62
- chips installed. It has thus been necessary to alter STOS again, now
- to Version 2.6.
-
- You must be aware of the changes from 2.3 upto 2.6. 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)
- on from the STOS Accessory disc 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 2.6,
- remember not to update your language disc unless the Complier contains
- a version greater than 2.6 - otherwise you'll be going back to square
- one!

-
- 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 (Version 2.4) 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 (Under 6s, 6-8s and Over 8s)
- can be updated using the same updater.
