Hi chuck,

>
> P[z]=z^{s-1}/(Exp[z-]-1)
>
> f[z]=1/(z^2-z^3)^{1/3}

o.k., I understand. I think that the advise of Jens-Peer will probably
be your best bet: Use some simple scheme to generate unique filenames,
either by just numbers or probably something that has more meaning in
case you look at the filenames without your customized GUI inteface.
Then create a look-up-table which gives you a connection form filename
to formula, either as just a list or probably even better in the form:
{filename -> formula, filename->formula}
then you can construct a custom Open/Save Dialog with the new feature
which displays the formula, but opens the corresponding filename. I
don't think there is a way to "overwrite" the menu item File/Save or
File/Open, but you could make a palette which makes your custom menus
available almost just as easy.
Here is a simple approach for a file-opener dialog which you probably
can build on. It defines a directory where you could put all your
notebooks and needs a rule as described abouve:
filenamerules={
"function1.nb"->Sqrt[z]/(1+z^2),
"funciton2.nb"->Sqrt[z]/(1+z^5),
"function3.nb"->Log[1+1/(Exp[z]Sqrt[z])]
};
functiondirectory=ToFileName[{$UserDocumentsDirectory,"Functions"}]
CreateDialog[
DynamicModule[{fn=filenamerules[[1,1]]},
Column[{
PopupMenu[Dynamic[fn],filenamerules],
Button["Open",NotebookOpen[ToFileName[{functiondirectory},fn]]]
}]]
]
Once you have this working you could think about all kind of extensions,
like generating the lookup-table automatically from the contents of the
files so you wouldn't have to fill that list manually. This could be
done by searching for e.g. Title-cells and display the expression which
is containd within those as the label for each file...
hth,
albert
