Here is mine:
#!/usr/bin/perl
use strict;
use warnings;
my $found_f = 0;
my ($lastline, $line);
open (INPUTFILE, "test.txt") or
die "Unable to open test.txt: $!"; # 'or die' Added
while (<INPUTFILE>)
{
chomp;
if (/^[A-Z]{2}:\s/) {
$lastline = $line;
$line = $_;
$found_f = 1;
}
elsif ($found_f) {
s/^ {4}/ /;
$line .= $_;
}
elsif (/^$/) {
$lastline = ' ';
$found_f =0;
}
} # Added
$lastline .= $line; # Added - this was your main problem
print "$lastline\n";
close (INPUTFILE); # Added
Notice how easier it is to read when you indent if and while statements? No wonder you missed the final }.
Update: Simplified second test (unnecessary RE) and removed
next, which is also unnecessary.
