Move (MOV)

The Move instruction moves the values from a V-memory
230
table to another V-memory table the same length. The
function parameters are loaded into the first level of the

240
accumulator stack and the accumulator by two additional
250-1
instructions. Listed below are the steps necessary to program

the Move function.
Step 1: Load the number of V-memory locations to be moved into the first level of the accumulator

Step 2: Load the starting V-memory location for the locations to be moved into the accumulator.

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

Pointer
In the following example, when X1 is on, the constant value (K6) is loaded into the
11
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
12
accumulator. The destination table location (V2030) is specified in the Move instruction.
