Most (Unix)

codice_1 is a terminal pager program on Unix, OpenVMS, MS-DOS, Windows and Unix-like systems used to view (but not change) the contents of a text file one screen at a time. Programs of this sort are called "pagers". It is similar to codice_2, but has the extended capability of allowing both forward and backward navigation through the file, and can scroll left and right. codice_1 also supports multiple windows.
Mats Akerberg, Henk D. Davids, Rex O. Livingston, and Mark Pizzolato contributed to early VMS versions of codice_1. Mark Pizzolato worked on it to get it ready for DECUS. Robert Mills re-wrote the search routines to use regular expressions.
