: xe33  $find invert IF ABORT THEN ;
: xe34
    " us" xe33 TO x9a7
    " case-closed?" $find invert IF 2drop ['] 0 THEN
    TO x9a8 ;

So the thing that throws is fcode e33, when trying to find the word "us".

(Btw, "invert" is weird here; I suppose it was coded as its synonym "not".
In some other Forth systems "not" is a synonym for "0=", which makes more
sense here.  Either works as long as $find returns a canonical true/false,
as it supposed to).

So, implement "us", and you'll get further :-)  It's just like "ms", but
microseconds, instead; so you could do

: us ( n -- )  d# 1000 / 1+ ms ;

(which waits way too long for short timeouts, of course).
