JulioHerrlein Posted March 9, 2021 Share Posted March 9, 2021 Dear All, I'm searching ways of making lists of lists. I tried all this because I was wanting to call materials from an array, like this: (setf mat1 '(c4 d4 ds7)) (setf mat2 '(d4 e4 c5)) (setf mat3 '(d4 eb4 cs5)) (setf mat4 '(d4 f4 c5)) (setf mat5 '(d4 g4 c5)) (setf mat6 '(d4 a4 c5)) (setf mat7 '(e4 a4 c5)) (setf mat8 '(f4 a4 c5)) (setf mat9 '(g4 a4 c5)) (setf mat10 '(a4 a4 c5)) (setf mat11 '(b4 a4 c5)) (setf array (build-array '((mat0 mat1 mat2 mat3) (mat4 mat5 mat6 mat7) (mat8 mat9 mat10 mat11)))) ;;;GET-ARRAY : (ROW COLUMN SIZE ARRAY &KEY DIRECTION (get-array 0 1 2 array :direction 'down) (setf listmat (get-array 0 1 2 array :direction 'down)) (list listmat) ; this does not work ; the result should be (list mat1 mat5) ((c4 d4 ds7) (d4 g4 c5)) What I did wrong ?
