|Writing a format to a variable?

Actually writing formatted text to a variable. And to be somewhat fair,
that's about the only way to do it in base perl4.

|How to do it better is

formline and $^A, mentioned in perlfunc.pod and described in more detail
in perlform.pod.

|(I don't use formats)

I don't use them often, but when I do, they save an enormous amount of time.
Formatting text always seems messier than it should be, but formats make it
pretty easy to do some complex stuff.
