I may have forgotten to credit you, but your "On Formally Unconvertable
Document Formats",[1] as well as other discussions re: markup vs.
presentation, were in mind when I was questioning procedural
representation. Especially your remarks about finding the third word
in a TeX document.

I don't (in some contexts) want a piece of code that opens a window and
prints a message asking me a question, etc. because, if I want to handle
this by an automated process, instead of interactively, I have
non-marked-up text to scan ( a program source ) to try to figure out what
it is doing. *If* the language can be constrained to higher level
functions that are trivially decipherable, then I suspect whatever it
does can be represented non-procedurally.
