I should have prefaced this message by saying that I sent the email to [EMAIL PROTECTED], as per the instructions "Address copyright, trademark, and permission issues to [EMAIL PROTECTED]" on http://www.wolfram.com/company/contact.cgi I presume that the answer is a legal one, then. > > By the way, webMathematica pro is very expensive -- it seems to > definitely be >$5,000 with an academic discount (it is hard to get a price, > as most places say you must call for a quote).

Import any AddOn package and type ??Function and you will see the source code, at least for any function that I've tried. Built-in functions don't reveal the source code, though, at least that I've noticed. Of course, you could read the source code for the AddOn packages too since they're just plain text files. I've sent a message back asking several other questions and for a few more specific clarifications. > >> * You may create your own functions in Mathematica, but cannot overwrite >> the built in functions.

I can understand the idea of trying to protect the validity of the built-in functions, but this also seems ridiculous given the official documentation: http://reference.wolfram.com/mathematica/tutorial/ModifyingBuiltInFunctions.html Thanks, Jason --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://sage.math.washington.edu/sage/ and http://sage.scipy.org/sage/ -~----------~----~----~----~------~----~------~--~---
