Maybe. I started with UCSD-Pascal but I do not remember whether it already had unsigned integer types. I just searched for its Length result type on the net and found that it was integer too. > - Expressions like length(s)-1 are very common and would cause a lot of > trouble if length(s) would be unsigned. That's true. But this only causes problems on zero-based arrays (strings are one-based and don't have this problem). > It is even easier to use a 64 bit OS in this case.

Thought it seems to bother others too: http://stackoverflow.com/questions/12781434/why-do-delphi-and-free-pascal-usually-prefer-a-signed-integer-data-type-to-unsig But on this link some other reasons for signed integers are given.. _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
