This should read, isn't it?

Code:

$i=0;
 while(<infile>)
 {
 ($file1,$file2)=split(/=/);
 $line1[$i]=$file1;
 $line2[$i]=$file2;
 $i++;
 }

thanks hong.....so array can be used using $ also is it .........no what the need of @ anyway?

thanks!

Actually, to refer to ONE element of am array or a hash, you SHOULD use $ instead of @. Perl will generate a warning if you use @ for this case if you have warning turned on.

From the perldata manpage (near the top):

Thanks a lot!! :-)

Hi, just a follow up question on split....

If we've a list of lines in the file such as the following...

1 a b c /* rrsss */
2 d e f /* reres */

If we want to split those after /* till end of line as array to be called later on, how can we do this without splitting each element by spaces..

($num, $x, $y, $z, @rest) = split (/\s+/, $_)

the @rest need to be associatively linked to $num..is it possible to do this directly without the need to split the @rest further...

Thanks in advance.
