Extending Control (from Fraktal SAS Programming)

Now, with proper declaration, it is safe to run your MACRO as a component in a validated system. However, it is still difficult to follow its results and discover failure risks or un-wanted misbehavior.

You might therefore find it useful to add functionality such as:

• Apply Logic: Check, branch and loop for specified parameters’ values
• Process Metadata: Navigate through the ecosystem by reading and processing metadata
• Workflow Documentation: Document workflow by writing comments to the LOG
• Realtime Information: Inform responsibles about invocation by sending an email

We will implement these requirements now step by step and thereby touch relevant parts of the so-called SAS Macro Facility.
