	SUBI -- Subtract immediate

SYNOPSIS
	SUBI	#<data>,<ea>

	Size = (Byte, Word, Long)

FUNCTION
	Subtracts the immediate data to the destination operand, and
	stores the result in the destination location. The size of the
	operation may be specified as byte, word, or long.
        The size of the	immediate data matches the operation size.
