If you formatted your code correctly, the reason becomes obvious.

You've added your until clause to the end of your foreach loop:

#!/usr/bin/perl-w ## To chop a sentence at intervals of 4-letter and to print results: use strict; my $sentence="BEAR CALF DEER FEAR GEAR HEAR"; ## To remove blank spaces: # Line 5 $sentence=~ s/\s//igs; print"\n Words are: \n"; do { my @four=$sentence=~ /[a-zA-Z]{4}/igs; # Line 9 foreach my $word(@four) { print"\n $word: "; my $length=length($word); print"\n Length of the word= $length\n\n"; my $output="Words .txt"; # Line 14 unless (open(RESULT,">$output")){ print"Cannot open file\"$output\".\n\n"; # Line 16 exit; } print RESULT"\n Words are: \n Word: $word; Length of the word= $length\n\n"; close(RESULT); # Line 21 } until ( my $word=~ /^.*$/); # Line 22 exit; }

With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.

The start of some sanity?
