Dear Stephen,

First I have a ready to use LargeIntegers plugin. A new version (minor
changes) with a precompiled module for Linux is coming soon. Note: there
is some En/Descryption stuff from other people with some LargeInteger
arithmetics, too.

Second I've worked at VM extensions for
- seamless integration of optional named plugins like optional numbered
plugins (caching of information that functions are missing),
- reloading modules (closing shared libs).

Look for postings today or tomorrow.



Last comments to LargeIntegers changesets:

"Change Set:		LargeIntegersPlugin
Date:			25 January 2000
Author:			Stephan Rudlof (sr at

Special thanks to:	Andrew C. Greenberg

Speeds up LargeInteger arithmetics.

Note: If you just want to use the LargeIntegersPlugin as an enduser,
	you do not need this change set!
	-> Look for a 'LargeIntegers' module (platform specific compiled
plugin) and the 'Install_LargeIntegers_module' change set then.


- VM 2.7 or later.


File in this change set and generate the module as library according the
'Short Guide for Compiling and Testing the LargeIntegersPlugin' found in
the postscript.

Then you will need the corresponding 'Install_LargeIntegers_module'

This change set binds the Integer classes with the LargeIntegers module
(compiled plugin).


- VM 2.7 or later;
- LargeIntegers module corresponding to your platform located in the
same directory as your 'squeak', '*.image' and '*.changes' files;
- Reading of the postscript 'Short Guide for Installing the
LargeIntegers module'!


It changes Integer methods
#digitAdd:, #digitSubtract:,
#digitMultiply:neg:, #digitDiv:neg:,

and Large(Positive/Negative)Integer methods #normalize.

They are changed as follows:
The module will be called, if it is switched on.
If it is switched off, the standard ST methods are applied.

If the module isn't reachable for any reason at startup, the standard ST
methods are called automatically. So there is no risk for installing
this change set.
