Another good use of a macro is with the database application where:
- database user can define the type of the object, for example,
database user "joe" could create new type named "bc evaluation"
- the type of the object is accessible to user only, not to other
users;
- user edits the type and declares that the value should be evaluated
with the external program named "bc". Such declaration could be
simple "bc" instead of complex programming
- macro generates a function specific for that user who needs to see
the output from "bc evaluation"
Thus it becomes a program that develops itself further based on
users's input.
