Limitations
The rightmost three digits of Di must each be between 0 and 3.
When the execution condition is OFF, MOVD(83) is not executed. When the
execution condition is ON, MOVD(83) copies the content of the specified
digit(s) in S to the specified digit(s) in D. Up to four digits can be transferred
at one time. The first digit to be copied, the number of digits to be copied,
and the first digit to receive the copy are designated in Di as shown below.
Digits from S will be copied to consecutive digits in D starting from the desig-
nated first digit and continued for the designated number of digits. If the last
digit is reached in either S or D, further digits are used starting back at digit 0.
