Convert field values from currency to numbers

I have a text file that is being read by a perl file. There is a field in the text file for Price. It is currently stated as currency (nothing past the decimal point). I want to remove the $ from those field values. Below is the code where it begins to read the file and then remove the field names so that they don't show up in search results.
I'm assuming it should happen before shift but I'm rather ignorant with perl....
my($ref, @listings);
$ref=&readlistings(); 
@listings=@$ref;
 
shift @listings; # get rid of header
foreach my $field (@FIELDS){
  $field=~s/[\-\:]//sg;
  $field=~s/^\s*//sg;
  $field=~s/\s*$//sg;
}
undef($ref);

What is in @FIELDS before, and what do you want in @FIELDS after?

And what about @listings?

ozo... I'm not sure what you mean...
I'll attach the entire cgi file(saved at .txt for uploading here). Basically the fields in the tab-delim text file are defined in the script and are also the first record in the text file. I believe shift was used in order to remove the field names from the array once the text file is read.

Where are the field values from which you want to remove the $

are you looking for something like
   s/\t\$/\t/g for @listings;

The field in particular is $listings{'Price'}
The values for that field used to be simply:
40,000
now it's
$40,000
as example - so now the portion of the script that performs a search based on a price range returns 0 results because the $ symbol is in the field value

Is this what you are trying to do?
 s/(\$[^\t]*)/join'',split'[$,]',$1/e for @listings;

Yes, I think so - though my problem is I don't know where in the code to put that.... :-(

woe about as soon as you assign @listings?
 s/(\$[^\t]*)/join'',split'[$,]',$1/e for @listings = @{&readlistings()};
(this assumes that COMPANY CODE does not contain a $, and that either Price always contains $ or that nothing else contains $)

Hiya - here's the snippet that I ended up using! Thanks so much for your help!
  s/(\$[^\t]*)/join'',split'[$,]',$1/e for @lines;
sub readlistings{
  open(FILE, $file) || &error("Could not open $file: $!");
  my @lines = <FILE>;
  @lines = reverse(@lines); 
  s/(\$[^\t]*)/join'',split'[$,]',$1/e for @lines; 
  close(FILE);
  return \@lines;
}
