I am still unsure as to what you want. To separate the blocks of number is easy. 
#!/usr/bin/perl -w
use strict;
$| =1;

my $curve1_out = 'curve1.out';
my $curve2_out = 'curve2.out';
my $in ='curve12.data';

open (IN,     '<', $in)         or die "cannot open $in $!";
open (my $c1, '>', $curve1_out) or die "cannot open $curve1_out $!";
open (my $c2, '>', $curve2_out) or die "cannot open $curve2_out $!";

while (<IN>)
{
   if (/^Curve(\d):/.../^\s*$/)
   { 
     if (defined($1) && $1==1 && /^\d/) {print $c1 "$_\n";}; 
     if (defined($1) && $1==2 && /^\d/) {print $c2 "$_\n"}; 
   }  
}

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, details, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, summary, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
  • You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)
            For:     Use:
    & &amp;
    < &lt;
    > &gt;
    [ &#91;
    ] &#93;
  • Link using PerlMonks shortcuts! What shortcuts can I use for linking?
