MULTIPLY02

MULTIPLY-CORRESPONDING

Basic form

MULTIPLY-CORRESPONDING rec1 BY 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 generates, for all field pairs corresponding to the sub-fields ni , statements of the form

MULTIPLY rec1-ni BY rec2-ni.

The other fields remain unchanged.

With complex structures, the full names of the corresponding field pairs must be identical.

Example

DATA: BEGIN OF MONEY,
        VALUE_IN(20) VALUE 'German marks'.
        USA TYPE I VALUE 100,
        FRG TYPE I VALUE 200,
        AUT TYPE I VALUE 300,
      END   OF MONEY,
      BEGIN OF CHANGE,
        DESCRIPTION(30)
            VALUE 'DM to national currency'.
        USA TYPE F VALUE '0.6667',
        FRG TYPE F VALUE '1.0',
        AUT TYPE F VALUE '7.0',
      END   OF CHANGE.
MULTIPLY-CORRESPONDING MONEY BY CHANGE.
MONEY-VALUE_IN = 'National currency'.

The above MULTIPLY-CORRESPONDING statement is equivalent to the following three statements:

MULTIPLY MONEY-USA BY CHANGE-USA.
MULTIPLY MONEY-FRG BY CHANGE-FRG.
MULTIPLY MONEY-AUT BY CHANGE-AUT.

Note

All fields with identical names are multiplied, whether numeric or not. The conversions performed are similar to those for MULTIPLY and the same runtime errors can also occur.
