From the manual:

"The unsigned binary value of the addend 1 operand is added to the unsigned
binary value of the addend 2 operand and the result is placed in the sum
operand."

"The addition operation is performed according to the rules of algebra. The
result value is then placed (left-adjusted) in the receiver operand with
truncating or padding taking place on the right. The pad value used in this
instruction is a byte value of hex 00. "

Example:

DCL DD A CHAR(68);
DCL DD B CHAR(68);
ADDLC(S) A, B;

A pratical use is hashing out a little checksum over some arbitrarily long
data.
