one digit (four bits) to the right. 0 is written into the leftmost digit of E and the right-
most digit of St is lost.

St must be less than or equal to E. St and E must be in the same data area.
The shift operation might not be completed if a power interruption occurs during
execution of the instruction.
Note Refer to page 115 for general precautions on operand data areas.
Flags ER (A50003): Content of *DM word is not BCD when set for BCD.
The St and E words are in different areas, or St is greater
than E.
Example When CIO 000000 is ON in the following example, 0 is shifted into digit 3 of
D00012, the contents of all digits in D00012 are shifted one digit to the right, the
content of digit 0 of D00012 is shifted to digit 3 of D00011, the contents of all dig-
its in D00011 are shifted one digit to the right, the content of digit 0 of D00011 is
shifted to digit 3 of D00010, the contents of all digits in D00010 are shifted one
digit to the right, and the content of digit 0 of D00010 is lost.
