Modifying a Subschema

When You Might Want to Make This Change

There are several modifications you may want to make to the subschema definition itself (other than modifications to set, area, and record definitions). These modifications include:

• Description
• Program registration
• Authorization
• Usage
• Information on transferring statistics
• Logical record currency
• Security
• User-defined information (class/attribute and user-defined comments)

What Components are Affected

The definition of the subschema as it resides in the dictionary is affected by such modifications.

Example

In the following example, program registration has been turned on. This requires that all programs using this subschema be registered with the named subschema in order to be compiled against it.
