Stephen,

For classes like this, you can probably use VB6 code too, so a google
search of "VB6 hash table class" (no quotes) brings up a few good
hits.

Good point - thanks !

Other than that, why not just use the Dictionary object from the
Microsoft Scripting Runtime library?

I'd rather like to have access to the source code to fine tune / debug.
And is the is Microsoft Scripting Runtime library bundled with all
plateforms runing XL2000, which is my minimum requirement ?!
Regards
