+/ 946 = sc1 How many 946's in sc1?
7
946 match sc1 NB. So we want to know where the 946's are.
NB. What gives? match doesn't see the 7 matches!
(sc1=946)#i.#sc1 NB. Try a different way.
7 19 30 50 125 141 208
946 match 50 {. sc1 NB. Try a smaller list of integers with match.
7 19 30 NB. That works.
946 match 100 {. sc1 NB. A little bigger works.
7 19 30 50
946 match 150 {. sc1 NB. Nope! match doesn't work on 150 integers.
946 944 match 50 {. sc1 NB. Let's try matching a short list of two
integers
7 19 30 NB. That works.
946 944 match 150 {. sc1
NB. That doesn't work.
It looks like match (I.@:E.) is limited to fairly small lists.
