in thread help with error 'readline() on unopened filehandle'

i understood that and updated the code as

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

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"	[reply]
