<CLS>
Syntax
<CLS>
Description
<CLS> takes the cursor to its home position and clears the screen. It
returns the string <ESC>h<ESC>J, which is the sequence of characters
needed to clear the screen on most Hewlett-Packard terminals.
Example
&PRINT <CLS> Welcome to HP Desk
This would clear the screen before printing Welcome to HP Desk on the top
line of the screen.
