No fair.  It's not editing itself, but rather a copy of itself.  I wrote
a code-file editor a while back that disassembled code interactively to
the screen, and allowed deletion/insertion of symbolic assembly statements.
Insertion was done by making room for the new statement by inserting
nop's and adjusting all references, then assembling the statement typed
and copying the machine code into the code file.  In the last stages of
development, I used the editor to modify its own executing code.  It
was sort of exciting.
