Interesting. The British X/Open organization defines a three byte return code 
of which two are in use. if char 1 is 1  or 2 then char 2 is the hexadecimal 
code for the function key  number, x'00' to x'0c' on a standard IBM style 
keyboard. Colors are defined in the same standard as 0 through 7, same as the 
OC array.  So I assume colors in a SCREEN definition can be relied on but 
return codes cannot, if one is programming for portability.
