Re^2: Unpack Bin file problem

OK, That worked. Your comment, "It sets the special variable to undef", is not yet clear to me. I will have to research this. I greatly appreciate you help. I understand the concept of $_, just not how local $/ modifies it.

It doesn't modify the behavior of `$_`, but of `<INFILE>` (for any handle). Perl has a bunch of special variables that change the behavior of perl. `$/` Is one of them, it changes what string readline, and thus `<INFILE>`, searches for as a line terminator, to read a whole line at once. When `undef`, it'll just make it slurp in the rest of the file.	[reply] [d/l] [select]
