Bug in FINDID:

The FINDID function in HP41 IL-module 82160A, MASS  ST  1H,  does
not  work correctly with IDs shorter than 7 characters.   This is
because it uses an internal  register  (M)  without  clearing  it
first.   As a fix, precede each FINDID with some instruction that
clears that register.   STO saves x there, so one  sequence  that
works  is CLX  STO X (immediately before FINDID).   It won't work
manually, though, nor with printer in TRACE mode.
