Description:
CERNLIB data analysis suite - KUIP terminal emulator
CERNLIB is a suite of data analysis tools and libraries created for use in physics experiments, but also with applications to other fields such as the biological sciences. . KXterm is a terminal emulator which combines the best features from the (now defunct) Apollo DM pads (like: input and transcript pads, automatic file backup of transcript pad, string search in pads, etc.) and the Korn shell emacs-style command line editing and command line recall mechanism. It can support the command-line interface of various CERNLIB applications.
