Directly Contained Programs and Indirectly Contained Programs
One program can contain another program directly or indirectly. Suppose a program, L,
contains another program, R. Program L directly contains program R when program L
does not contain any other program that also contains program R. Program L indirectly
contains program R if program L does contain any other program that contains
program R.
In Figure 2-2, all the programs are in the same run unit and:
