[Oberon] RX.Tool scope limited to 1 line ?

[Aubrey.McIntosh at Alumni.UTexas.Net]

I found that the three search strings here work separately, but when I
try to concatenate them, I receive a line too long error.  The next
step might be to do a replace of the complicated strings with some
relatively simple constant string in 1 pass, so that RX doesn't get
lost.

RX.SetSearch { i | t | " " }  c
RX.SetSearch { i | t | " " }  " dog" c
