Here is the code based on your example: 
#!/usr/bin/perl

use warnings;
use strict;
use Getopt::Std;

my %options;
getopt("ivcm",\%options);

do {
 die "Usage: $0 -i <input file> -v <variable file> -c <code file> -m <
+macro file>\n" unless defined $options{$_}
} for qw/i v c m/;


open my $input, "<", $options{i} || die "$options{i}: $!\n";
open my $code, ">", $options{c} || die "$options{c}: $!\n";
open my $var, ">", $options{v} || die "$options{v}: $!\n";
open my $macro, ">", $options{m} || die "$options{m}: $!\n";

while (defined(my $line = <$input>)) {
    chomp $line;
    next if $line=~/^\s*$/;
    next if $line=~/^\s*\*/;
    $line=~s/EQU\s+\*//;
    $line=~s/\s*$//;
    my @fields = split /\s+/,$line,4;
    shift @fields until $fields[0] ne '';
    if ($fields[0] eq 'BEGIN') {
        print $code join ("\t",@fields),"\n";
    } elsif ($fields[0] =~ /^(BEGIN|L|CLI|BNE|LTR)$/) { #code
        pop @fields;
        print $code (join "\t",@fields),($fields[0] eq 'CLI' ? "" : "\
+n");
    } elsif ($fields[0] =~ /^@/) { # macro
        print $macro (join "\t",@fields),"\n";
        pop @fields;
        print $code (join "\t",@fields),"\n";
    } elsif ($fields[1] =~ /^D[CS]$/) { #variable?
        my ($len) = ($fields[2] =~ /L(\d+)/); #???

        print $var (join "\t",$fields[0],$len,$type,$value,$fields[3])

It sure contains some mistakes because I had to guess some things about CLI, BNE and variables. Feel free to fix it. If you would state more clearly how to distinguish between code and variables, it will be easier to write the proper code.
See split, join, shift, pop for more info on this script.
Sorry if my advice was wrong.
