Re: Splitting file into separate files based on record lengths and identifiers

Hope this will help you. Uses Hash.

 
#!/usr/bin/perl -w
# 

use warnings;
use strict; 
my %hash = ();
while (<DATA>) {
    chomp($_);
    my $n = length($_);
    my $i = 0;
    while ($i<$n) {
        my $long = substr($_,$i,4);
        $i += 4;
        my $delim = substr($_,$i,1);
        $i += 1;
        my $val = substr($_,$i,$long);
        $i += $long;        
#        print $long,' ',$delim, ' ', $val,"\n";
        $hash{ $delim } .= $val.',';
}    }
s/,\z// for values %hash;

while ( my ($key, $value) = each(%hash) ) {
      print "$key => $value\n";
      }

print "size of hash:  " . keys( %hash ) . ".\n";
print '-' x (60),"\n"; 

__DATA__
0004$ADAM0002*330004%19770004$BOB 0002*430004%1967
0003$XDA0002*440004%22220003$XOB0002*990004%3333

Results.

The hash solution intrigued me, but it seems to break when I make the strings longer, can someone enlighten me as to why? Sample data:

0100$THIS IS A 100 CHAR FIELD £$%£%$£                                                               0030*THIS IS A 30 CHAR ONE

Thanks!

It is working fin for me. The £ sign comes out funny because I an in Latinamerica and using the standard character set.
