Hello,
How can I set a requirement for <STDIN> (e.g. require the <space> to
continue running the program)?
It is not clear what you are asking. Posting a sample program would
really help.
If you are asking if it is possible to pause a program and wait for a
specific user input, you can capture the input and test it:
my $response = <STDIN>;
chomp($response);
exit unless $response =~ /whatever/;
One problem with this approach is that the user must enter a return
to unpause the program. If you want the user to be able to enter a
single character (other than a return), see, for example, 'perldoc -q
single' "How can I read a single character from a file? From the
keyboard?".
