BCD Calculation Instructions Section 5-20
Description When the execution condition is OFF, ADDL(54) is not executed. When the
execution condition is ON, ADDL(54) adds the contents of CY to the 8-digit
value in Au and Au+1 to the 8-digit value in Ad and Ad+1, and places the
result in R and R+1. CY will be set if the result is greater than 99999999.
Flags ER: Au and/or Ad is not BCD.
Indirectly addressed DM word is non-existent. (Content of *DM word
is not BCD, or the DM area boundary has been exceeded.)
CY: ON when there is a carry in the result.
EQ: ON when the result is 0.
Example When 00000 is ON, the following program section adds two 12-digit numbers,
the first contained in LR 00 through LR 02 and the second in DM 0010
through DM 0012. The result is placed in HR 10 through HR 13.
The rightmost 8 digits of the two numbers are added using ADDL(54), i.e., the
contents of LR 00 and LR 01 are added to DM 0010 and DM 0011 and the
results is placed in HR 10 and HR 11. The second addition adds the leftmost
4 digits of each number using ADD(30), and includes any carry from the first
addition. The last instruction, ADB(50) (see 5-21-1 BINARY ADD – ADB(50)
adds two all-zero constants to place any carry from the second addition into
HR 13.
