As just one of many examples of functions I've written that get used over
and over again, my CheckInputFile() function is used in pretty much any
program that requires filenames to be passed at the command line.  You pass
the value of the argument variable where the file is located (or empty
string if none) and a default extension (if applicable) and it will expand
the filename and path, checking they exist, and prompt the user if there are
any problems.

The trick  to making modular programming useful is to make your functions
generic.
