In this chapter, you learned
how to understand complex Visual Basic Applications
that contain multiple modules and procedures
that require sharing data between each other.
When writing programs with several modules and
procedures, you must keep in mind the variable
scope so that procedures have access to the
data they need. Moreover, we discussed about
several internal functions.
