Interpreting Text

[Oliver Bandel]

Hello,

how can I interpret a text and use the input
for creation of symbols?

I think about using keywords, which will be
read from the document, but not set as words,
which they are.

Words which are in a list of keywords should be
evaluated to special postscript-shapes.
The words of the input are the names for the
shape and the shapes are the evaluated representation.

I don't want to write an "@" in front of each
keyword. Most of the different shapes are combinations
of more basic ones.



Questions:
  1.: How to use such lists in lout?
  2.: Is it better to write global definitions for
      each of the shapes, or is it better (and possible)
      to use _one_ definition, which will interpret a list
      of keywords (which are only readable in such an
      environment?).
  3.: How to implement the postscript-shapes?
  4.: Is it a more accurate to write this solution
      directly in postscript?


Thanks in advance,
              Oliver
