PackageID uniqueness

[Genesis1701d1]

I'm trying to understand publishing packages (in my case using a stored process), and I'm looking at this example from the documentation:

https://documentation.sas.com/?docsetId=publishdg&docsetTarget=n1xvf6fybwq7pvn1j8qt77ech1xz.htm&docs...

In particular, they define two packages. One is the main package:

packageId = 0;
   nameValue="type=(test) coverage=(filtering, transports)";
   CALL PACKAGE_BEGIN(packageId,"Main results package.",
      nameValue, rc);

And one is a secondary package that gets nested in the first later on:

gifpid=0;
   CALL PACKAGE_BEGIN(gifpid,"Gif nested package.",'', rc);

Both of these packages have a package ID of 0. How can that work? Isn't the packageID supposed to uniquely identify a package?

Yes, the package ID uniquely identifies the package.  I think a zero value for the ID after calling PACKAGE_BEGIN indicates that the cal failed.  Check the return code value.

data _null_;
packageId=0;
rc=0;
desc = 'Nightly run.';
nameValue='';
CALL PACKAGE_BEGIN(packageId, desc, nameValue, rc);
putlog packageId= rc=;
run;
