There is a pretty common mistake that people make when typing in this 
program.  Because the text is Helvetica (i.e. a proportional font), the 
following line is often mis-typed since the space character isn't as wide
as the other characters:

   () dup 0 charcode put outsideplacechar

should really be:

   ( ) dup 0 charcode put outsideplacechar
%  (^add space here)

There's another line further down in the program that needs to be changed
in a similar manner.  The reason this bombs is that the put operator is
trying to put a value into a string which has no storage associated with
it.

Good luck...
