RE: Overlapping subfields with a MOVE

Move is a CPYBRA operation. The target is implicitly substring'd with the
source length. But also the "P" operation extender may be used.
Some lower-level instructions do not always work well when the source and
the target overlap in memory.
There is a specific instruction memmove() that does just that, and is
written to handle the situation where the source and target overlay one
another.

Hey Eric,

It took me awhile to discipline myself to read all replies before replying 
to an email.  Especially when returning from vacation.  Welcome back.
