According to Hans Ecke:

A last question: What is the schema of the automatic type-conversion? Is there a global schema for converting between ordinal,real and string types or is it only done from case to case?

What do you mean by "automatic type-conversion" between ordinal, real, and string types? Assignments like "ordinal:= real" or "string:= integer" are - of course - simply illegal in Pascal. You can assign an integer to a real, but not vice versa. Am I missing something? Peter Dipl.-Phys.
