The first procedure that is executed in a process can issue EXEC commands internally to call other procedures. This is called nesting. Regardless of how many other procedures are called, or the number of nesting levels involved, all execute as part of the same process. If any procedure in a process issues a START command, a new process is invoked, which is independent of the originating process.
Execution of the procedures in a process continues according to the logic of the procedures. When the first level procedure completes its processing, it ends and the process terminates.
