Growth of strings in context dependent Lindenmayer systems, problems concerning the decidability of growth equivalence, growth type classification etc. of context dependent growth are shown to be undecidable. As a byproduct we obtain that the language equivalence of PDILs is undecidable and that a problem proposed by Varshavsky has a negative solution.

Notes on pre-set pushdown automata,l AFL. If all conditions are removed, present pda‘s exactly represent the family of iterated regular substitution languages, a sub-family of the indexed languages. Deterministic preset pda‘s are also studied, and the language-family they define is shown to be closed under complementation, generalizing a classical result.

Structured OL-systems,morphisms) of OL-Languages. The properties of unrestricted SOL-systems are then studied. It is for example shown that the languages generated by them properly include the languages generated by extended table OL-Systems.

Theory of L systems: From the point of view of formal language theory,ch year fruitful and popular. This is exemplified by exponential growth of the number of papers produced (per year), and a linear (with a decent coefficient) growth of both the number of results and the number of people joining the area..(2) It may have already occurred to the reader (and it is cert
