FDB - Form double byte constant:

[label]	FDB	expression[,expression,...,expression]

The FDB directive may have one or more operands separated by commas. The 16-bit value corresponding to each operand is stored into two consecutive bytes of the object program. The storage begins at the current program counter. If a label is present it is assigned the address of the first 16-bit value. Multiple operands are stored in successive bytes. The operand may be a numeric constant, a character constant, a symbol, or an expression. If multiple operands are present, one or more of them can be null (two adjacent commas), in which case two bytes of zeros will be assigned for that operand.



Example:
	fdb	$0000
fdb $0010,$3343,$EDA4
