When the execution condition is OFF, ASL(060) is not executed. When the ex-
ecution condition is ON, ASL(060) shifts a 0 into bit 00 of Wd, shifts the bits of Wd
one bit to the left, and shifts the status of bit 15 into CY.

Flags ER (A50003): Content of *DM word is not BCD when set for BCD.
CY (A50004): Receives the status of bit 15.
EQ (A50006): Content of Wd is 0 after a shift.
N (A50008): Same status as bit 15 of D + 1 after shift.
Example When CIO 000000 is ON in the following example, 0 is shifted into bit 00 of
D00010, the status of all bits within D00010 are shifted left one position, and the
status of bit 15 is shifted to CY.
