Many of the DL05 series instructions will allow V-memory pointers as a operand
(commonly known as indirect addressing). Pointers allow instructions to obtain data
from V-memory locations referenced by the pointer value.
NOTE: DL05 V-memory addressing is in octal. However, the pointers reference a
V-memory location with values viewed as HEX. Use the Load Address (LDA)
instruction to move an address into the pointer location. This instruction performs the
Octal to Hexadecimal conversion automatically.
In the following simple example we are using a pointer operand in a Load instruction.
V-memory location 2000 is being used as the pointer location. V2000 contains the
value 440 which the CPU views as the Hex equivalent of the Octal address
V-memory location V2100. The CPU will copy the data from V2100 which in this
example contains the value 2635 into the lower word of the accumulator.
