Since I am new to perl I am getting acquitted with perl syntax. In one of the script I found the line,

$centerPoints{MID}{1} = ($nbnodex-1)*$lele/2;

G'day AbhiKulk01, Welcome to the Monastery. `MID` is not a keyword! In `$centerPoints{MID}{1}`, `MID` is the name of a hash key. You can read about this, and lots of other interesting information for those just starting out with Perl, in perlintro: Perl introduction for beginners. — Ken	[reply] [d/l] [select]

It's only a hash key, a string "MID", it's the same like `$centerPoints{"MID"}{"1"}` see `perlintro` for more Cheers Rolf _{(addicted to the Perl Programming Language and ☆☆☆☆ :) Je suis Charlie!}	[reply] [d/l]
