This command sets the pen color for the input line, message line, run indicator and edit screen. KBD LINE PEN overrides any previous ALPHA PEN for these areas of the screen. The pen-number is a numeric expression rounded to an integer. If you are using the bit-mapped display driver legal values are from 0 to 15. (HP BASIC supports values to 255.) If you are using the non-bit-mapped display driver, legal values are from 136 to 143. This statement is equivalent to CONTROLCRT,17;pen-number.
