Editing DEC Text Processing Utility (section)

== Functionality ==
TPU provides text buffer management APIs in concert with window management APIs which are targeted for the [[VT100]] line of terminals.{{citation needed|date=January 2020}}  This allowed split-screen windows with scrolling and hence multiple views of the same buffer content.{{citation needed|date=January 2020}}  There are also key mapping APIs provided, allowing a wide range of functionality for editing text. The keyboard mapping could be easily adapted by  the admin or the user.{{citation needed|date=January 2020}}

Users could write their own specific editor, to e.g. translate text or short (error) messages to multiple natural languages in a synchronised small text window. The text editor is callable, so you could have small text editors built into specific applications, e.g. a simple mail client. You might redirect output from applications into a text window, using [[inter-process communication]]. Therefore one could call web services to return their results into a text buffer.
