To invoke the command interpreter, run one of the front ends. The command-line arguments can be specified by the "Parameters" field in the objects' properties notebook if one is starting the command interpreter from a Program object on the Workplace Shell Desktop.
The command interpreter front ends will either accept command lines interactively, in one of several ways depending from what front end one uses, or will process command lines read from command scripts. Each line that is read is parsed into a sequence of commands that are then executed.
The behaviour of the command interpreter can be controlled by setting
various
environment variables,
either in the parent process that starts the command interpreter or at
runtime with the built-in
SET command.
