Suffix m\.  u\.  _ 0 _ Outfix

u\.y has #y items resulting from applying u to suffixes of y , beginning with one of length #y (that is, y itself), and continuing through a suffix of length 1 .

m\.y applies successive verbs from the gerund m to the suffixes of y , extending m cyclically as required.
 
  If x>:0 in x u\. y , then u applies to outfixes of y obtained by suppressing successive infixes of length x . If x<0 , the outfixes result from suppressing non-overlapping infixes, the last of which may be a shard.

x m\.y applies successive verbs from the gerund m to the outfixes of y, extending m cyclically as required.
