Precautions
If the number of digits being read or written exceeds the leftmost digit of S or D, MOVD(083) will wrap to
the rightmost digit of the same word.
Sample program
When CIO 0.00 is ON in the following example, four digits of data are copied from W0 to W100. The trans-
fer begins with the digit 1 of W0 and digit 0 of W100, in accordance with the control word’s value of 31.
Note After reading the leftmost digit of S (digit 3), MOVD(083) wraps to the rightmost digit (digit 0).
