Refer to page 101 for general precautions on operand data areas.

ER (A50003):

Number of bits to shift is out of range.

Content of a*DM word is not BCD when set for BCD.

CY (A50004):

"1" has been shifted to CY.

Content of words D and D+1 after the shift is all zeros.

Same status as leftmost bit (MSB) of word D+1 after shift.

When CIO 000000 is ON in the following example, the 32 bits in D00201 and

D00200 are shifted three bits to the left. The status of the three rightmost bits of

D00200 are set to "0."
