NJ-series Instructions Reference Manual (W502)
The array variable stcA[0..9] is used as a stack. As preparations, three values (UINT#1111,
UINT#2222, and UINT#3333) are stored in the stack.
The StackPush instruction is used to store a new value (UINT#4444) at the top of the stack stcA[3].
That means there will be four values in the stack.
Then, the StackLIFO instruction is used to remove one value at the top of the stack stcA[3]. That means
there will be three values in the stack.
