well the value is 4, so if i subract 3 it should go down too 1 should it not?. Like this works if i try to subract 1, but if i try to subract anything higher i get an error

I should have been more clear -- what is the actual value?
[code]
var books : flexible array 1..4 of int 
put "the actual value is: ", lower (books) - 3
[/code]
