This instruction is available in the CQM1 only.
TB1 and TB1+15 must be in the same data area.
TB2 and TB2+15 must be in the same data area.
DM 6144 to DM 6655 cannot be used for R.
When the execution condition is OFF, MCMP(19) is not executed. When the
execution condition is ON, MCMP(19) compares the content of TB1 to TB2,
TB1+1 to TB2+1, TB1+2 to TB2+2, ..., and TB1+15 to TB2+15. If the first pair
is equal, the first bit in R is turned OFF, etc., i.e., if the content of TB1 equals
the content of TB2, bit 00 is turned OFF, if the content of TB1+1 equals the
content of TB2+1, bit 01 is turned OFF, etc. The rest of the bits in R will be
turned ON.
ER: One of the tables (i.e., TB1 through TB1+15, or TB2 through TB2+15)
exceeds the data area.
Indirectly addressed DM word is non-existent. (Content of *DM word
is not BCD, or the DM area boundary has been exceeded.)
EQ: ON if the entire contents of both tables are equal and R=0000.
