Defining a Database Using Non-SQL › Defining a Subschema › AREA Statements

AREA Statements

AREA statements identify areas to be included in this subschema. The area descriptions are copied from the schema area descriptions. Depending on the verb and options coded, the AREA statements can also:

• Determine the usage modes in which programs using the subschema can ready the area
• Determine the default usage mode for programs that do not issue READY statements
• Modify, delete, display, or punch a subschema area

The subschema compiler applies AREA statements to the current subschema.

Procedure

1. Name the area
2. Optionally specify usage modes that are not allowed
3. Optionally specify default usage mode for the area

Note: The default for usage modes is that the mode is allowed. Specify those usage modes you do not want allowed.

Example

The following example shows the definition of the area ORG-DEMO-REGION being copied into the current subschema.

add area org-demo-region
  exclusive update is not allowed
  default usage is shared update.
