I don't know why your program ends up editing Ans instead of LIST_1, maybe Cyrille can provide some insights on how parameters are managed for EDITLIST.

However here is a way to edit the list defined by ID:

Code:

NUMBER:=1;
ID:="LIST_"+NUMBER;  // ID  ="LIST_1"

EXPR("EDITLIST("+ID+")"); // LIST_1:={ 1,2,3 } CHANGE LIST_1:{100,200,300}
