thanks a lot for your answer. i have not enough skills to write my own print.default routine, though. i thought there should be a user-option that allows to change the default behaviour. anyway, whats the idea of printing 1e-04 instead of 0.0001 and what is the appropriate topic in the help-pages or faq?
