A block consists of one or more words. A word consists of an address
followed by a number some digits long. (The plus sign (+) or minus sign
(–) may be prefixed to a number.)
Word = Address + number (Example : X–1000)
For an address, one of the letters (A to Z) is used ; an address defines the
meaning of a number that follows the address. Table 13.2 (b) indicates
the usable addresses and their meanings.
The same address may have different meanings, depending on the
