Nested HP COBOL Programs
Nested HP COBOL programs are contained in other HP COBOL programs. Nested
programs can be directly or indirectly contained. In Figure 23-1, the compilation unit
contains two separately compiled programs (Mane and Sub), which contain nested
programs, and the programs have these relationships:
The program ... Directly contains ... And indirectly contains ...
Mane Aaa, Bbb Ccc, Ddd
Aaa Nothing Nothing
Bbb Ccc Ddd
Ccc Ddd Nothing
Ddd Nothing Nothing
Sub Nothing Nothing
