My experience is that memory block manipulation, as a replacement for
string manipulation, is not noticeably slower than the original BASIC
calls, despite the multiple lines of code. On the contrary even, at least
when the BASIC program gets compiled - memory block manipulation seems to
benefit strongly from compilation, up to a factor of 40, where the overall
performance of compiled BASIC rarely exceeds a factor 2, compared to the
interpreted source.

Kind regards,
