Clears the active windows and returns the cursor to the upper-left corner.
Declaration:
procedure ClrScr;
Remarks:
Sets all character positions to blanks with the currently defined
text attributes. Thus, if TextBackground is not black, the entire
screen becomes the background color.
This also applies to characters cleared by
ClrEOL,
InsLine and
DelLine, and to empty lines created
by scrolling.
ClrScr is window-relative.
