The Fill( command takes an existing list or matrix variable and sets all its elements to a single number. It doesn't return anything and only works on already defined variables.

{5}→dim(L1)
Fill(2,L1)
L1
{2 2 2 2 2}

{3,4}→dim([A])
Fill(1,[A])
[A]
[[1 1 1 1]
[1 1 1 1]
[1 1 1 1]]

= Optimization =

When creating a new list or matrix you want to fill with zeroes, it's better to delete it then create it with [[TI-BASIC:Dim|Dim(]], which will set all entries to 0, than to set its dimensions with dim( (which may not clear what was there before) then use Fill(.

= Errors =

On a TI-84+CSE, using Fill(List,List) will cause a RAM clear. For example: Fill({1,2,3},{1,2,3} will cause a RAM Clear. this does not apply on any other models, only giving you argument and data type errors.
