Details

A DS2 package is a collection of variables and methods of which particular instances can be constructed and used in other DS2 programs.

You declare a PCRXFIND package variable using the DECLARE PACKAGE statement. After you declare a PCRXFIND package variable, use the _NEW_ operator to instantiate an instance of the PCRXFIND package and assign the new package instance to the PCRXFIND package variable.

declare package PCRXFIND finder;
finder = _new_ PCRXFIND();

declare package PCRXFIND finder;
finder = _new_ PCRXFIND();

As an alternative to the two-step process of using the DECLARE PACKAGE and the _NEW_ operator to declare and instantiate a logger package, you can declare and instantiate the package in one step by using the DECLARE PACKAGE statement as a constructor method. Here is the same example using only the DECLARE PACKAGE statement.

declare package PCRXFIND finder();

Note: Package variables are subject to all variable scoping rules. For more information, see Packages, Scope, and Lifetime in SAS DS2 Programmer’s Guide.
