Re^4: help with error 'readline() on unopened filehandle'

[bhargavkanakiya]

i understood that and updated the code as

...
    open my $MYFILE , "<$filename" || "Can't open the output file!";
...

then the error changed to 'readline() on closed filehandle $MYFILE' even though i have not closed the file. this is the first code that i've written using perl and i am completely new to it. any help is appreciated. thanks.

Different guy here, see Tutorials: Basic debugging checklist , run your code to B::Deparse, then use or instead of || , it is a classic precedence pitfall, see || die or or die :), "or die" versus "|| die"

bah, corrected link "or die" versus "|| die", and two more To || or not to or and why., Perl Idioms Explained - && and || "Short Circuit" operators
