Try it like this (changes in red)
Code:
#!/usr/local/bin/perl
use strict;
use warnings

my $DATABASE = "/home/myfile/DATABASE_DIR";

open_my_doc( "Pricelist" );

sub open_my_doc {
print "$DATABASE/$_[0]\n"; 
open(my FH, "< $DATABASE/$_[0]" ) or die $!;
        while (<FH>) {
          print $_;
        }
        close FH;
}

use strict and use warnings help catch a lot of programmatic errors that otherwise would only show themselfs later (maybe even only as heisenbugs).
Calling perl -c <script> does a syntax check without running it, so that syntactic error (like your last }) can be found.
I suggest installing perltidy, as it will clean your code in terms of indentation and unneeded clutter (like ; at the end of blocks when they aren't needed)

NAME

       setcolor - redefine or create a color

SYNOPSIS

       setcolor color red_level green_level blue_level

DESCRIPTION

       The  setcolor  command  takes four arguments: color, which must be a string naming the color; and the arguments red_level, green_level, and
       blue_level, which must be integer values defining, respectively, the intensity of the red, green, and blue components of  color.   Intensi-
       ties  must  be  in the range of 0 to 1000. If you are redefining an existing color, you must use its current name (default color names are:
       black, blue, green, cyan, red, magenta, yellow, and white). setcolor returns the color's name string.
