↑RLNL(262)
When the execution condition is OFF, RLNL(262) is not executed. When the ex-
ecution condition is ON, RLNL(262) shifts all bits previously in Wd and Wd+1 to
the left, and bit 15 of Wd+1 is shifted into both bit 00 of Wd and into CY.

WdCY
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.
CY (A50004): Receives the status of bit 15 from Wd+1.
EQ (A50006): Content of Wd and Wd+1 are 0 after execution.
N (A50008): Same status as bit 15 of Wd+1 after execution.
Example When CIO 000000 is ON in the following example, the status of bit 15 of
CIO 0101 is shifted into bit 00 of CIO 0100 and into CY, the status of all bits within
CIO 0100 are shifted left one position, the status of bit 15 is shifted to bit 00 of
CIO 0101, and the status of all bits within CIO 0101 are shifted left one position.
