Ever written any Pascal?  Therein lies madness.

All these fixed length character strings are a poor man's solution.
Dynamic structures aren't that hard to code up, and once you have
the right library routines it's trivial to use them with future code.
Code them once, use them everywhere.

Only today, did my mail user agent trash the RFC 822 address parser
because it [the parser*] decided that lines _never_ exceeded 256
characters.  My user agent says lines are long as you've got virtual
memory for.  So it's time to persuade the parser about dynamics.

Should be easy.
