# setting range of indices in an array with a constant value

 P: 51 Hi i'd like to set a range of indices in a list with one constant value. for example if list = [ 1 2 3 4 5 6] then list(1..4,6) = 9 will change 'list' as so it now equals = [ 9 9 9 9 5 9] i tried \$list(1..4) = 9 but it only set the first index cell how this action can be done ? thanks, May 11 '08 #1
