getting error in my perl script

hi
Here is my code written to identify the particular position which is after a string (chr*). my input file looks some thing like this

Code:

aaanbb:anhn:iuopl:12345 chr1 12345 asnmkol * # kjiiii.....anmkij:lpolk:lopll:abnnj chr5 123222 polko * dddfgg ....

aaanbb:anhn:iuopl:aanjuj chr2 44345 asnmkol * # kjiiii.....anmkij:lpolk:lopll:abnnj chr7 567222 polko * dddfgg ..

i wanted to get the @pos as the immediate occurance after chr* as there are 2 such occurances in each line the first occrance has to be stored in pos[0] and second in pos[1] for pos[0] pattern search has to be made wih in pos[0]+6 characters and same vs for pos[1] but backwards

Code:

use strict;
use warnings;
open (my $fhConditions, "<1.txt"); 
my $l=6;
open (my $read, "<2.txt");
my @e = <$read>;
my $d = join('', @e );
$d =~ s/\s+//g;
while (my $line = <$fhConditions>) {
chomp $line;
my @pos = $line[$i] =~/chr*\s+(.+?)\s/g;
if($pos[0] =/[0-9]/)
{
my $match = substr($d,$pos[0],$l)
print "$line" if $match =~m/AAGCTT/;
}
if($pos[1] =/[0-9]/)
{
my $a = $pos[0]-$l;
my $match = substr($d,$a,$l);
print "$line" if $match =~m/AAGCTT/;
}
}

request_scroll

request_scroll(3alleg4) 					  Allegro manual					   request_scroll(3alleg4)

NAME

       request_scroll - Queues a hardware scroll request with triple buffering. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       int request_scroll(int x, int y);

DESCRIPTION

       This  function  is  used for triple buffering. It requests a hardware scroll to the specified position, but returns immediately rather than
       waiting for a retrace. The scroll will then take place during the next vertical retrace, but you can carry on running  other  code  in  the
       meantime and use the poll_scroll() routine to detect when the flip has actually taken place.

       Triple  buffering  is only possible with certain drivers: you can look at the GFX_CAN_TRIPLE_BUFFER bit in the gfx_capabilities flag to see
       if it will work with the current driver.

RETURN VALUE

       This function returns zero on success, non-zero otherwise.
