I'm trying to recode data using (=&OLD } ,:&NEW) but the following happens both on J7 and J64-602:
(3 1 4 1 5 9 = 1) } 3 1 4 1 5 9,:_1 NB. OK 3 _1 4 _1 5 9 (=&1 } ,:&_1) 3 1 4 1 5 9 NB. not OK 9 1 4 1 5 9 _1 _1 _1 _1 _1 _1 A=. (=&1 ; ,:&_1) 3 1 4 1 5 9 NB. check args of } B=. (3 1 4 1 5 9 = 1) ; 3 1 4 1 5 9,:_1 A-:B 1 Any suggestions? (I might be missing something obvious as I've spent much of the night analysing a clinical trial!)
