The RMQ directive causes the location counter to be advanced by the value of
the expression in the operand field multiplied by 2. This directive reserves a
block of memory the length of which is equal to the value of the expression
multiplied by 2.The block of memory reserved is not initialized to any given
value. The expression cannot contain any forward references or undefined
symbols. This directive is commonly used to reserve a scratchpad or table area
for later use.
