| Tally | # _ 1 _ | Copy |
#y is the number of items in y . Thus: (#'');(#'a');(#'octothorpe') +-+-+--+ |0|1|10| +-+-+--+ (#3);(#,3);(# 3 4) +-+-+-+ |1|1|2| +-+-+-+ (#i.4 5 6);(#$i.4 5 6) +-+-+ |4|3| +-+-+ |
If the arguments have an equal number of items, then x#y
copies +/x items from y, with i{x
repetitions of item i{y .
Otherwise, if one is an atom it is repeated to make the item
count of the arguments equal. The complex left argument a j. b copies a items followed by b fills. The fit conjunction provides specified fills, as in #!.f . |
