Assignment of Data into an MDO

The &ASSIGN OPT=DATA option is the default and can be used to set MDO components from:

• Another MDO component
• One or more NCL variables
• User-supplied data

When assigning into an MDO component of a simple type from NCL variables or constant data, the input supplied must be in the valid external form for the component type or a type check results.

When assigning into an MDO component of a simple type from another MDO component the input selected must have a local form valid for the target component type. If the types are different, type conversion takes place where possible. Otherwise, a type check results.

When assigning into an MDO component that is a constructed type, the following conditions must be satisfied:

• The data must be valid in its physical format according to the structuring rules for the target component.
• Each embedded component must be in its valid local form.

If the conditions are not satisfied, a type check results.

Note: For more information about the external form and local form of data for each type, see Managed Object Development Services Guide.
