Function
•
Substitutes the content of s into d.
•
It is possible to use array variables for d and s.
•
When d is a word, the constant is
When d is a double word, the constant is
Notes
•
When using an array variable, DER is set to 1 if the usable I/O number exceeds the maximum value, and DER is reset to "0"
if it is normal.
•
The combinations of d and s are as follows:
