5-25-3 LOGICAL OR – ORW(35)
Limitations
DM 6144 to DM 6655 cannot be used for R.
Description
When the execution condition is OFF, ORW(35) is not executed. When the
execution condition is ON, ORW(35) logically OR’s the contents of I1 and I2
bit-by-bit and places the result in R.
Example
Flags
ER:
Indirectly addressed EM/DM word is non-existent.
(Content of
*
EM/
*
DM word is not BCD, or the EM/DM area boundary
has been exceeded.)
EQ:
ON when the result is 0.
5-25-4 EXCLUSIVE OR – XORW(36)
Limitations
DM 6144 to DM 6655 cannot be used for R.
Description
When the execution condition is OFF, XORW(36) is not executed. When the
execution condition is ON, XORW(36) exclusively OR’s the contents of I1 and
I2 bit-by-bit and places the result in R.
