Step 1: Decide on a feature to implement
The
first step in building a PowerBuilder extension is to identify a
problem that an extension can solve. This might be a feature that
can be coded more efficiently and easily in C++ than
in PowerScript, or that requires the use of callback functions or
nonstandard datatypes. You might also have access to existing C++ classes
that perform the tasks you want to add to a PowerBuilder application,
or you might want to create a wrapper for existing standard utilities written
in C++.

extensions".
