The example to the right shows a table of two words at V3000
and logically ORs it with K8888. The copy of the table at
5
V3100 shows the result of the OR operation for each word.
The program to the right performs the ORMOV example
6
above. It assumes that the data in the table at V3000 – V3001
already exists. First we load the table length (two words) into
7
the accumulator. Next we load the starting address of the
source table, using the LDA instruction. Then we load
the data into the accumulator to be ORed with the table.
8
In the ORMOV command, we specify the table
destination, V3100.

The example to the right shows a table of two words at V3000

and logicall XORs it with K3333. The copy of the table at
V3100 shows the result of the XOR operation for each word.
A
The ladder program example for the XORMOV is similar to
the one above for the ORMOV. Just use the XORMOV
instruction. On the handheld programmer, you must use the
B
SHFT key and spell "XORMOV" explicitly.

Load the constant value 2

bits of the accumulator.
LDA
Convert otal 3000 to HEX

Copy the table to V3100,
