Need help understanding perl script error

I solicited this site earlier this week and got a good answer for a perl
Script so I made this script from what understood from the answers
But now I have a bug and I'm stump. It doesn't parse correctly the
Output it stays on the first line My $f2 and reprints in a endless loop
I'm sure there are better ways than this. But this is what I want to solve
Dan

This is the script

Code:

 
#!/usr/local/bin/perl -w
use strict;
 
die "Usage: $0 <file1> <file2> <file_out>\n" unless $#ARGV==2;
my ($file1, $file2, $file3) = @ARGV;
 
open my $f1_in, $file1 or die "Could not open $file1\n";
open my $f2_in, $file2 or die "Could not open $file2\n";
open(my $f3_out, '>', $file3) or die "Could not open $file3: $!\n";
 
while (my $f1 = <$f1_in>) {
my $f2 = <$f2_in>;
$f1 =~ s/^\s+|\s+$//g;
$f2 =~ s/^\s+|\s+$//g;
 
#$\ = "\n";
my $FS = '|';
$, = ',';
 
my $Fld0 = shift;
my $Fld1 = shift;
my $Fld2 = shift;
my $Fld3 = shift;
my $Fld4 = shift;
my $Fld5 = shift;
my $Fld6 = shift;
my $Fld7 = shift;
my $Fld8 = shift;
my $Fld9 = shift;
my $Fld10 = shift;
 
while ($f2){
($Fld0,$Fld1,$Fld2,$Fld3,$Fld4,$Fld5,$Fld6,$Fld7,$Fld8,$Fld9,$Fld10) = split(/[|\n]/,$f2, -1);
print $f3_out ($Fld0, $Fld1, $Fld2, $Fld3, $Fld4, $Fld10);
}
}

merge_fonts

merge_fonts(3alleg4)						  Allegro manual					      merge_fonts(3alleg4)

NAME

       merge_fonts - Merges two fonts into one font. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       FONT *merge_fonts(FONT *f1, FONT *f2)

DESCRIPTION

       This function merges the character ranges from two fonts and returns a new font containing all characters in the old fonts. In general, you
       cannot merge fonts of different types (eg, TrueType fonts and bitmapped fonts), but as a special case, this function can  promote  a  mono-
       chrome bitmapped font to a color font and merge those. Example:

	  FONT *myfont;
	  FONT *myfancy_font;
	  FONT *lower_range;
	  FONT *upper_range;
	  FONT *capitals;
	  FONT *combined_font;
	  FONT *tempfont;
	  ...
	  /* Create a font that contains the capitals from  */
	  /* the fancy font but other characters from myfont */
	  lower_range = extract_font_range(myfont, -1, 'A'-1);
	  upper_range = extract_font_range(myfont, 'Z'+1, -1);
	  capitals = extract_font_range(myfancy_font, 'A', 'Z');

	  tempfont = merge_fonts(lower_range, capitals);
	  combined_font = merge_fonts(tempfont, upper_range);

	  /* Clean up temporary fonts */
	  destroy_font(lower_range);
	  destroy_font(upper_range);
	  destroy_font(capitals);
	  destroy_font(tempfont);

RETURN VALUE

       Returns a pointer to the new font or NULL on error. Remember that you are responsible for destroying the font when you are finished with it
       to avoid memory leaks.
