 Changes the default character for screen clear
------------------------------------------------------------------------------
 Syntax

     SETCLEARB([<cClearCharacter|nClearCharacter>])
        --> cNull

 Argument

     <cClearCharacter|nClearCharacter>  Designates the desired clear
     character for CLEARB.  Can be a number in the range of 0 to 255 or the
     character string type.  The default value is CHR(255).

 Returns

     SETCLEARB() always returns a null string.

 Description

     SETCLEARB() sets the default character for screen-oriented CA-Clipper
     Tools functions.  If this function is not called within a program,
     character CHR(255) is used by the clearing functions.  This character
     (a "hard"' blank) can accept a color attribute on all screen adapters.

 Note

     .  When you call SETCLEARB() without designating the
        <cClearCharacter|nClearCharacter> parameter, the standard character
        CHR(255) is used.

 Examples

     .  Use CHR(255) as the standard character:

        SETCLEARB()

     .  Use CHR(178) as a clear character SETCLEARB(178)
