• Step 1 Load the number of V-memory locations to be moved into the first level of the accumulator
stack. This parameter is a HEX value (KFFF max, 7777 octal, 4096 decimal).
• Step 2 Load the starting V-memory location for the locations to be moved into the accumulator.
This parameter is a HEX value.
• Step 3 Insert the MOV instruction which specifies starting V-memory location (Vaaa) for the
destination table.
Helpful Hint: — For parameters that require HEX values when referencing memory locations,
the LDA instruction can be used to convert an octal address to the HEX equivalent and load
the value into the accumulator.
In the following example, when X1 is on, the constant value (K6) is loaded into the accumulator
using the Load instruction. This value specifies the length of the table and is placed in the first
stack location after the Load Address instruction is executed. The octal address 2000 (V2000),
the starting location for the source table, is loaded into the accumulator. The destination table
location (V2030) is specified in the Move instruction.

Table Instructions
Move (MOV)
The Move instruction moves the values from a V-memory table to
another V-memory table the same length (a table being a consecutive
group of V-memory locations). The function parameters are loaded
into the first level of the accumulator stack and the accumulator
by two additional instructions. The MOV instruction can be used
to write data to non-volatile V-memory (see Appendix F). Listed
below are the steps necessary to program the MOV function.
