Discussion
This subroutine is provided for compatibility with BasicX. The more aptly named MemCopy() should be
used by new applications. An overlapping copy (when the destination is in the midst of the data being
copied) is handled correctly so that the data to be copied is not overwritten.
Compatibility
With VM firmware versions prior to v1.1.0 an overlapping copy is not handled correctly nor is it handled
correctly in BasicX. A BasicX application that relies on the incorrect handling will, therefore, not work as
expected when run on ZX processors.
