Introduction
The command shell is a line oriented user interface. Commands are
typed and the results are displayed on the screen. The commands shell
is similar in operation to the Unix csh(1) program.
Commands may span physical lines. Commands MUST be terminated with a
semi-colon ';'.
Upon startup, the command shell will attempt to execute commands in
the file '.dbcshrc'. If this file does not exist in the current
directory, the command shell will give an error message saying so, and
will continue.
The following variables have special meaning to the command shell:
