Description
SR7
SR8
(ER)
To be set in case of out-of-range values in indirect access (index modification).
To be set in the case that the length of the target data for [S3] is 0.
To be set in the case that the control data specified by [S1] is out of the specified range.
To be set when [S2 + calculation starting po S3] exceeds the [S2] area.
To be set when the address specified by [D + storage starting position] exceeds the [D] area.
