indx ← brks ##.range nums                   ⍝ Numeric range classification.

Each  item  of the result shows to which sub-range within the left  argument the
corresponding  item  of the right argument belongs. Values below the first break
report  0,  and  those above the upper break report ⍴⍵. A value is judged within
a  sub-range if it is greater-or-equal to the lower bound and strictly less than
the upper bound:  ⍺[i] ≤ ⍵ < ⍺[i+1].

Range was supplied by Veli-Matti Jantunen.
