RE: (Recursive) nested loops and IFs?
(12-17-2015 08:20 PM)chromos Wrote: In this case you have to use ΠLIST: ΠLIST(list) returns the product of the list elements which is the equivalent of a Boolean AND while ∑LIST(list) returns the sum of the list elements which is the equivalent of a Boolean OR. Nested IF conditions can be replaced by ANDs: PHP Code: IF (EXPR(L5(1))>=0 AND EXPR(L5(1))<=9) THEN is the same as: PHP Code: IF (EXPR(L5(1))>=0 AND EXPR(L5(1))<=9) AND (EXPR(L5(2))>=0 AND EXPR(L5(2))<=9) AND (EXPR(L5(3))>=0 AND EXPR(L5(3))<=9) THEN EXECON("EXPR(&1)>=0 AND EXPR(&1)<=9",L5) returns a list with the result of the test for each element of L5, either 0 (false) or 1 (true). Then ΠLIST returns the product (AND) of all these results: 0 (false) if at least one is false and 1 (true) if all are true. As we work with lists this is not tied to the number of variables.

Here L4-L3 returns a list of the differences between the elements of L4 and L3, so ΠLIST(L4-L3) returns the product of these differences which gives the total number of loops to do. |
