#!perl
# Simple Perl script for partial testing of a Win32 perl install.
# This script tests some of Perl's standard I/O and file funcions.

# the new file will NOT be created and the program quits.

# created. If you don't answer 'yes' it tells you what happened and
# suggests you use DEL at a DOS prompt to delete the file instead.
