When I was working in APL in the 1980s there used to be a utility function called'Tree': TREE'F0' F0 ..F1* ..F2 ....F2_1* ......F2_1_1* ....F2_2* ..F3* i.e. an indented list of function calls.(The real functions would have names).
Has anyone done anything similar for J? ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
