In the following example, when X1 is on, the constant value 3544 is loaded into the
accumulator. This is the value that will be output to the specified offset V-memory location
(V1525). The value 3544 will be placed onto the stack when the LDA instruction is executed.
Remember, two consecutive LD instructions places the value of the first load instruction onto
the stack. The LDA instruction converts octal 25 to HEX 15 and places the value in the
accumulator. The OUTX instruction outputs the value 3544 which resides in the first level of
the accumulator stack to V1525.

Out Indexed (OUTX)
The OUTX instruction is a 16 bit instruction. It copies a 16 bit
or 4 digit value from the first level of the accumulator stack to a
source address offset by the value in the accumulator(V-memory
+ offset).This instruction interprets the offset value as a HEX
number. The upper 16 bits of the accumulator are set to zero.
