Curses

Libraries for character oriented user interfaces with standardised UNIX functions that provide rudimentary screen handling and updating of text-based windowing. It is a very basic API and is commonly used on UNIX like systems as a sort of lowest common denominator for a text user interface. Curses libraries are available for various operating systems. Although most commonly used with a text mode C programs the API can also be used from other programming languages and is quite often used with scripting languages such as REXX.

The name "curses" is a pun on "cursor optimization" and the software concept and name it traces its roots to terminal libraries from the early 70's and appears to pre-date UNIX even.
