Define Action Blocks

An action block is a named collection of action statements that do not directly support an elementary process. A common action block is an action block invoked by more than one process or procedure. A business algorithm is an action block invoked through a USE action or a SET USING action.

Defining logic for action blocks consists of the following activities:

• Create new action block in Analysis or Design
• Define logic for action blocks
  • Define algorithm for derived attributes
  • Define algorithm for designed attributes
• Reference common action blocks in process and Procedure Action Diagrams
  • Specify business algorithm in SET USING statements
  • Specify business algorithm in USE statement
• Define external action blocks
  • Add EXTERNAL designation
  • Define import and export views

The following topics discuss these activities.
