I think you want this pair of expressions:
<@({.~ i.&' ');._2 text
0 1 }. _&".;._2 text
(Note that giving ". a left argument tells J that you only want
numeric results. When you do this, you don't need to do the search and
replace, because J recognizes - as being a minus sign. Also, since
you've assigned a numeric value for non-numbers, the first word
appears in the final result for each line, where you can drop it.)
Thanks,
