Comparison Instructions Section 5-19
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.)
GR: ON if Cp1+1,Cp1 is greater than Cp2+1,Cp2.
EQ: ON if Cp1+1,Cp1 equals Cp2+1,Cp2.
LE: ON if Cp1+1,Cp1 is less than Cp2+1,Cp2.
Example:
Saving CMPL(60) Results
The following example shows how to save the comparison result immediately.
If the content of HR 10, HR 09 is greater than that of 011, 010, then 10000 is
turned ON; if the two contents are equal, 10001 is turned ON; if content of HR
10, HR 09 is less than that of 011, 010, then 10002 is turned ON. In some
applications, only one of the three OUTs would be necessary, making the use
of TR 0 unnecessary. With this type of programming, 10000, 10001, and
10002 are changed only when CMPL(60) is executed.
5-19-5 MULTI-WORD COMPARE – MCMP(19)
Limitations 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.
Description 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.
