It is because you are using
"$recno^$qno^$vtext"; in your print statement, but they aren't declared in the block.
For Example:
my $a = <STDIN>;
if($a eq 'y'){
my ($fname, $lname) = ('tom', 'test');
print "$fname $lname\n"; #OK because vars declared in block
}
print "$fname $lname\n"; #Vars are out of scope now, will die under st
+rict
Your code should look something like this, so your vars can be used between loop iterations.
#!/usr/bin/perl
use strict;
use warnings;
open (IN, "infile") or die "Can't open input file: $!\n";
open (OUT, ">outfile") or die "Can't create outfile for write: $!\n ";
my ($junk,$qno,$junk2,$vtext,$recno);
while (<IN>) {
if (/^##recstart/) {
($junk,$recno) = split;
$recno =~ s/'//g;
}elsif (/^##v/) {
($junk,$qno,$junk2,$vtext) = split (/ /,$_,4);
$qno =~ s/'//g;
$vtext =~ s/'//g;
}else {
print OUT "$recno^$qno^$vtext";
}
}
