(BF)

Mnemonic: (BF)
Hex equivalent: "@0406@"
Discussion: Blank fill.

The (BF) control code replaces all characters from the cursor position to the end of the line with blanks. The current mode -- foreground, background, or invisible (suppressed background) -- determines the type of blank. When this control is complete, the cursor is positioned at the beginning of the next line (or the next available foreground position on the screen).

This control code may also include a positioning statement to start the fill operation from a specific point on the screen.

Example: 
a. 100 FORMAT (SB);(BF),@(10,0)
   .
   PRINT (0,100)

b. PRINT (0) (SB);(BF),@(10,0)
This example sets the video mode to background (SB), and then blank fills the top row of the screen (i.e., row 0) from position 10 to the end of the line.
