SCREEN ERASE_CHARS

SCREEN ERASE_CHARS erases characters in a window by replacing them with blanks. The remaining text in the window is not moved. An erase operation is limited to the specified line. If the number of characters is greater than the number of characters remaining in the line, all characters from the starting position to the end of the line are erased. The cursor is positioned at the first erased character.
