What is the difference between “AS” and “IS” in an Oracle stored procedure?

Question

I see Oracle procedures sometimes written with \"AS\", and sometimes with \"IS\" keyword.

CREATE OR REPLACE Procedure TESTUSER.KILLINSTANCE (INSTANCEID inte         


        

Answer 1

According to TutorialsPoint

The AS keyword is used instead of the IS keyword for creating a standalone procedure.

and considering previous answers,

I guess

AS is for stand alone (outside of any block, subprogram, package) entities

and

IS is for embedded (within a block, subprogram or package) entities.
