──────────────────────────────────────────────────────────────────────────────

 Syntax

     ClearEOL([<nRow>], [<nCol>], [<cAttr | nAttr>], [<cChar | nChar>]) 
          --> cNull

 Arguments

     <nRow>  is the line to be cleared. The default is the current line.

     <nCol>  is the column to start from. The default is the current column.

     <cAttr | nAttr>  is the attribute used to clear.  The default is "W/N"
     or 7.

     <cChar | nChar>  is the character used to clears. Default is CHR(255)

 Returns

     ClearEOL() always returns a NULL string, or "".

 Description

     ClearEOL() may be used to clear a specific line, using a specific
     colour, from a given position to the end of the line without affecting
     the Clipper ROW() or COL() functions.

     If you do not specify a colour attribute character, [<cAttr | nAttr>],
     then CLEARA is used.

     If you do not specify a character to clear with, [<cChar | nChar>],
     then CLEARB is used.

 Notes

     ■  If a window is currently selected, the this function will be applied
        to the window.

     ■  If no parameters are used the current line will be cleared from the
        current cursor position to the end of the line.

     ■  This function does not alter the cursor position.

 Examples

     ■  Clear from the cursor position to the end of the line assuming a
        default colour character of "W/N", starting at the current cursor
        position.

        ClearEOL()

     ■  Do the same for bottom of the current window or application window
        from the current cursor position:

        ClearEOL( MaxRow() )

     ■  Clear the bottom of the current window, but begin at 10 chars from the end:

        ClearEOL( MaxRow(), MaxCol()-10 )

     ■  The attributes can be specified in different ways:

        ClearEOL( MaxRow(), MaxCol()-10, 4 )         // red on black
        ClearEOL( MaxRow(), MaxCol()-10, "4,7" )     // red on white
        ClearEOL( MaxRow(), MaxCol()-10, "B/W" )     // blue on white

     ■  Clear with special attribute and character:

        ClearEOL( MaxRow(), MaxCol()-10, "3/1", ":" )
        ClearEOL( MaxRow(), MaxCol()-10, "3/1", "+" )
