I once thought of writing an article about all the goofy
ways people have devised to count the lines in their files.
(Have you ever wondered why we are so attached to columns
of data? I wonder if it has something to do with the hard-wiring
in our brains. Something about bananas hanging from the top of
a tree, maybe.)

Anyway, IDL 5.6 has FILE_LINES, which will give us
all a consistent way to count lines from now on. Now,
all we have to do it convince everyone to upgrade... :-)

Cheers,

David
