Hi,
If you want to split one file into lot of files use that pattern as your record separator, that is $/.
Try this one ... 
#! /usr/bin/perl -w

my $infil = $0;
my $separator = "XXFFDDF";
local $/ = $separator;

sysopen(INFIL,$infil,O_RDONLY) || die "Can't open $infil: $!.\n";
while(<INFIL>){
  my $out_file = "$infil.$.";
#  s/$separator//;
### if you want to remove your file separator also, uncomment above li
+ne .....
   sysopen(OUT,$file,O_RDWR|O_CREAT|O_EXCL) || die "Can't open for wri
+te tst.$.: $!.\n";
  print OUT $_;
}
close(INFIL);
