the current directory. If the directory does not exist an appropriate

environment variable.
ii. clr - Clear the screen.

iv. environ - List all the environment strings.
v. echo - Display on the display followed by a
new line (multiple spaces/tabs may be reduced to a single space).
vi. help - Display the user manual using the more filter.
vii. pause - Pause operation of the shell until ''Enter'' is pressed.
viii. quit - Quit the shell.

it was executed).
