Thanks to everybody for their replies. I use this post to comment on them. "Curtis Osterhoudt" wrote > I tried a direct response, but my demunging wasn't crafty enough for >your email's reply-to. I'm sorry for that. But munging is the best defense I've tried so far against spamming. This year I received only 2 spam messages. At any rate, "mynick @ despammed . com" (without spaces and quotes) would do - I will prolly revise my tagline. >The documentation for TransformationFunctions (with which I haven't >played, but wish I knew about far, far earlier) indicates that if the >user includes a list of transformations to try, only those are used.

Being used to work chiefly on version 3, I was not aware of this particular improvement (which I will soon investigate - especially Andrzej's 'take a peek' code- so thanks to you and the other posters for the tips). But, as you said, it approaches the solution the other way round and the user might want to just skip a particular simplification that comes out in the output of Mathematica. It would be nice to be able to exclude, for example, the hypergeometric functions from a simplification. I will experiment a little with TransformationFunctions and ExcludedForms options of Simplfy and FullSimplify in the future, but from what I've read in the documentation there is no easy way to exclude certain rules from the simplification process. The only way I can think of would be to build a simplification routine from scratch, by adding tons of simplification rules and by excluding those for the hypergeometric functions. cheers, Peltio Invalid address in reply-to.
