2. Extended Addressing is a type off
addressing in which memory
addresses/ memory location are
inputted instead of exact data.
3. In this type, the memory where the
data would be stored is given in forms
of LDAA & LDAB; the storing address o
the answer is also given along with the
starting address for the I.R.O.
4. The number sign, in this
addressing, is not included (in the
OMML table; MNEMONICS
column).
5. Some changes also affects the
mnemonics. The mnemonic for
LDAA & LDAB changes from 86 and
C6 to B6 and F6.
6. In this type of addressing, the I.R.O.
Procedures (Input, Run, Output
Procedures) would vary a
bit, where some parts would be
added.
7. A part called
would be added after the first part
which is inputting the procedure.
