in reply to need a clearer understanding

... while($line = <$IFH> ){ chomp $line; if(not($line eq "")) { ##### why does $line equal "" ? my @tmp = split(//,$line); ...

what does $line = ""; mean?

If the "#####" comment is anything to go by, then a test for "not empty line" is being done in "not( $line eq "" )".

In that case your question is actually different than the comment, where you assign an empty string to $line variable.

    I think he means ($line eq "")
