Hi Andy,

I think you want to look at marker.  From gforth:

marker forget1  ok
: hello ." Hello One " cr ;  ok
marker forget2  ok
: hello ." Hello Two " cr ; redefined hello   ok
hello
Hello Two
  ok
forget2  ok
hello
Hello One
  ok
forget1  ok
hello
:55: Undefined word
>>>hello<<<
Backtrace:
$7FBA4EB4 throw
$7FBB1618 no.extensions
$7FBA502C interpreter-notfound1
