BCD Format 0 (C=#0003)
When CIO 0.01 is ON in the following example, the signed BCD data format
and range in D300 are checked against the format specified in the control
word (0003). The source data is correct, so the signed BCD data in D300 is
converted to signed binary and output to D400.
3-11-15 DOUBLE SIGNED BCD-TO-BINARY: BISL(472)
