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. 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 to FFFF.
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 instructions 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.
