Could I please get an example of this?  I see lots of examples of how to do it in C but when I try to translate to pascal I always struggle a quite a bit.

Is there a way I can detect that a user has pushed the red X in the upper right corner to close the console window in a free pascal console application so I can save some files before the program terminates?

You can do that with SetConsoleCtrlHandler() and catching  CTRL_CLOSE_EVENT in the handler.
