(DT=,DT<>,DT>,DT<=,DT<,DT>=)
Function
(1) This instruction compares the date data specified by with those specified by , or the
date data specified by with current date data. Setting n can determine the data to be
compared.
(a) Comparison of given date data
• This instruction treats the date data specified by and as a normally open
