Any options for better interactive terminal-style I/O?

[Dave Britten]

Right now, the Prime just has PRINT(), which can clear the screen, or print a line of text. There's also the INPUT() function, but that displays full-screen input forms, much like INFORM on the 48.

Are there any libraries floating around that provide more traditional interactive terminal I/O? Like the sort of thing you'd get with Disp/Input on a TI, or Write/WriteLn/ReadLn in Turbo Pascal, or PRINT/INPUT in just about any old version of BASIC.
