MULTIPLY-CORRESPONDING

Short Reference

Other versions: 7.31 | 7.40 | 7.54

Obsolete Syntax

MULTIPLY-CORRESPONDING struc1 BY struc2.

Effect

This statement, which is forbidden in classes, multiplies structures in terms of components. Structures must be specified for struc1 and struc2. All components with the same name in struc1 and struc2 are multiplied with each other in pairs and the result is assigned to the appropriate component of struc1.

The names are compared, as in the statement MOVE-CORRESPONDING. For each component pair with the same name comp, the statement

MULTIPLY struc1-comp BY struc2-comp.

is executed, and the appropriate conversions are performed, if necessary.

Note

This statement is error-prone because, particularly in complex structures, it is not easy to check that components of the same name have the data type and content necessary for a numeric operation.
