Listed below are the steps necessary to program the Fill function.
Step 1: Load the number of V-memory locations to be filled into the first level of the
accumulator stack. This parameter must be a HEX value, 0–FF.
Step 2: Load the starting V-memory location for the table into the accumulator. This parameter
must be a HEX value.
Step 3: Insert the Fill instruction which specifies the value to fill the table with.
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 (K4) is loaded into the accumulator
using the Load instruction. This value specifies the length of the table and is placed on the first
level of the accumulator stack when the Load Address instruction is executed. The octal address
1600 (V1600) is the starting location for the table and is loaded into the accumulator using
the Load Address instruction. The value to fill the table with (V1400) is specified in the Fill
instruction.

Fill (FILL)
The Fill instruction fills a table of up to 255 V-memory locations
with a value (Aaaa), which is either a V-memory location or a
4-digit constant. The function parameters are loaded into the
first level of the accumulator stack and the accumulator by two
additional instructions
