Rob,
this is really a quick-draw shot from the hip, & will probably be
shamefacedly apologized for later, but having said that, couldn't one
check for the presence of one or more Any characters? sort of like
#using $_
unless /.+/ {print "nothing here\n"}
regards,
bill naftel

Subject: Dumb Question: How to check if a string is empty
This is sad....
How do you check to see if a string is empty?
my $stuff
while($stuff "I don't know)
{
print "You must enter a value\n";
$stuff = <STDIN>;
}
Any help is appreciated....
Rob
