Inputting Numbers Up to BufSize
Each time the instruction is executed, the value of In is stored in Buf[CurIndex]. The average of CurIn-
dex + 1 numbers that start from Buf[0] is calculated and stored in Out.
When the number of instruction executions reaches BufSize, the value of Q changes to TRUE.
Second Execution of Instruction

CurIndex=def
2345
In=abc
Third Execution of Instruction
CurIndex=def 2
In=abc 3456
Inputting Numbers after Reaching BufSize
Each time the instruction is executed, Buf[0] to Buf[BufSize
cyclic fashion. The average of Buf[0] to Buf[BufSize
The value of CurIndex returns to 1 after it reaches BufSize and it is then incremented again. The value
of Q remains TRUE.
Fourth Execution of Instruction

In=abc 4567
Fifth Execution of Instruction
