The composite of operands must not contain more than 18 digits. The com-
posite is the data item resulting from superimposing all operands, aligned
by decimal points. The data items that follow GNING are not included in the
composite. The compiler insures that enough places are carried to avoid
loss of significant digits during execution.
If one or more of the additions results in a size error, the procedure RATE-
OVERFLOW - PROC is performed after completion of the whole ADD statement.
Each receiving item that has a size error retains its current value instead of
the computed result. Control returns to the statement following ADD statement.
