Segment
The Segment instruction uses the character specified by
IN to generate a bit pattern (OUT) that illuminates the
segments of a seven-segment display. The illuminated
segments represent the character in the least significant
digit of the input byte (IN).
Error conditions that set ENO = 0: SM4.3 (run-time),
0006 (indirect address)
Figure 9-45 shows the seven segment display coding
used by the Segment instruction.
