About the CLS Command
CLS does not issue a form feed. CLS replaces the the NEWPAGE command in DOS to Windows conversions, which does issue a form feed. The additional CLS options pertain only to DOS versions of R:BASE.
Example
The following example clears the window from row 7 column 5 to row 9 column 60, and sets the background color in the cleared region to red.
CLS FROM 7,5 TO 9,60 RED
