DDE Library Function Overview

The DDE Library includes functions specifically for Microsoft Windows DDE support. This
section contains general information about the DDE Library functions and panels.

The DDE Library Function Panels

The DDE Library function tree appears in Table 6-1. The first- and second-level bold headings in
the tree are the names of function classes and subclasses. Function classes and subclasses are
groups of related function panels. The third-level headings in plain text are the names of
individual function panels. Each DDE function panel generates one or more DDE function
calls. The names of functions are in bold italics to the right of the function panel name.
