Summary:

Question: The function TrnGetPen gives hardware alarm if there is no such pen. Can I use this function so that it will not create an hardware error if the pen does not exist?

Solution:

In Version 3.00 and later TrnGetPen will not generate a hardware error if the pen does not exist. It will just return an empty string.
