Doug, Unfortunately, no, at this point, there is no way to undefine a local variable. If it goes out of scope (e.g. when you exit the function in which Fri, 01 May 2009 23:14:56 GMT Doug Edmunds http://tech.groups.yahoo.com/group/frink/message/238 http://tech.groups.yahoo.com/group/frink/message/238 I ran the example from the documentation for graphics: g = new graphics. However in the units.txt datafile, g is used for the gram units.

As of the current release, the behavior of the abs[x] function is changed for interval arguments (real or complex arguments are not changed.)

The short answer is that I'm following the convention for abs[x] that's defined in one of the seminal works on interval arithmetic, Ramon Tue, 14 Apr 2009 07:18:35 GMT Alan Stebbens http://tech.groups.yahoo.com/group/frink/message/232 http://tech.groups.yahoo.com/group/frink/message/232 I probably don't understand intervals well enough yet, but if x = new interval[-2,2] [-2,2] and x^2 [0, 4] then why doesn't abs[x] yield [0,2]?
