StackDel
The following example is for when Size is UINT#6, Num is UINT#3 and Offset is UINT#1.
• When an element in the array is passed to InOut[], all elements below the passed element are pro-
cessed.
• The values in InOut[] and Num do not change if the value of Size or Num is 0.
• Return value Out is not used when the instruction is used in ST.
• An error occurs in the following cases. ENO will be FALSE, and InOut[] will not change.
• The values of Num and Size are not 0 and Size is not greater than or equal to Num and Num is
not greater than Offset.
• The value of Size exceeds the array area of InOut[].
