CANDE
CANDE (Command AND Edit) is a command line shell and text editor on the MCP (Master Control Program) operating system which runs on the Unisys Clearpath series of mainframes. Originally implemented on Burroughs large systems, it has a range of features for interacting with the operating system execution environment, focused on executing, editing and compiling programs, and creating, copying, moving, renaming, and deleting files in general.

Its full name is CANDE MCS. MCS, or Message Control Subsystem is the general form of a systems program in the Burroughs architecture (other than MCP, the Master Control Program or core OS). As an MCS, CANDE is more than just an editor as it provides overall control for a network of users.
The editing capabilities of CANDE are anachronistic for casual (as opposed to scripted) editing as they predate full screen and graphical editors.
CANDE was also used on the Burroughs CMS (mini computer) range, with very similar syntax.
In contemporary MCP, CANDE is primarily used thru the ODT (Operator Display Terminal) and MARC (Menu Assisted Resource Control) on emulators of the original character oriented terminals as with other legacy mainframe interfaces such as ISPF.
