C++ Virtual Functions

[Complete]

Hi
    I was wondering if people who are coding their Palm apps in  C++,
tend to use virtual functions (and how) or tend to shy away from them
due to their use of Global data.

In 'Palm Database Programming' Eric Giguere suggests either
1) avoid them
2) simulate them
3) relaunch app  ( not supported by palm) if Global variables are not
available e.g. find function
