Hi, I have a verb such as:
v1 =: {{)m a=.L.y b=.2^1-~a c=. (<y)(<0 0 0)}<"0[0$~a,b,4 d=.2&^i.a e=.a$0 ...complicated verb... }} where in complicated verb, I am supposed to have a nested iteration on i.a then i.d and mutate y from v1 on each iteration. I have tried to emulate a nested loop with {{ x ] F.. {{ x ] F.. + y }} y }} but I cannot understand the order of execution. Also, is there a way to reference x from v1 in the nested loop to mutate it? Perhaps nested loops would be the preferred way here? Thanks!
