Dear monks:
I have the following pretty simple subroutine which finds and returns the next non-empty, non-comment line in an input text file. Comments are lines beginning with "#". dprint() is a printing sub for debugging.
sub nextline {
my $fh = shift;
my $l;
do {
$l = <$fh>;
if (!defined($l)) { dprint "end of file\n"; return undef }
dprint "line is: $l";
next if ($l =~ /^#/); # skip comments
$l = clean($l);
} until ($l ne ''); # skip blank lines
return $l;
} ## end sub nextline
This code works perfectly, but for every comment in the input file, Perl complains (even without strict):
Exiting subroutine via next...
What kind of trouble can doing it this way cause, or why is Perl complaining?
Thanks kindly,
Vacant
