//***************************************************
// This program lists all the files ending with .pas
// in the current diectory using the built-in
// procedure "exec".
// Basically the program determines whether it is running
// under a Unix-like platform or not and passes
// the approprate list command to "exec" along
// with the "*.pas" argument so that only files
// ending with .pas are listed.
