ADD-CORRESPONDING

Basic form ADD-CORRESPONDING rec1 TO rec2.

Effect Interprets rec1 and rec2 as field strings. If, for example, rec1 and rec2 are tables, executes the statement for their header lines. Searches for all sub-fields which occur both in rec1 and rec2 and then, for all relevant field pairs corresponding to the sub-fields ni, generates statements of the form

ADD rec1-ni TO rec2-ni.

The other fields remain unchanged. With complex structures, the complete names of the corresponding field pairs must be textually identical.

Example
DATA: BEGIN OF VECTOR,
X TYPE I,
Y TYPE I,
LENGTH TYPE I,
END OF VECTOR,
BEGIN OF CIRCLE,
VOLUME TYPE P
Y TYPE P,
RADIUS TYPE I,
X TYPE I,
END OF CIRCLE.

…
ADD-CORRESPONDING VECTOR TO CIRCLE.

The sub-fields X and Y occur in both the field strings VECTOR and CIRCLE. Therefore, the ADD-CORRESPONDING statement is equivalent to both the following statements:

ADD VECTOR-X TO CIRCLE-X.
ADD VECTOR-Y TO CIRCLE-Y.

Note All fields with the same name are added, whether numeric or not. The same conversions are performed as with ADD and similar runtime errors to those possible with ADD can also occur.
