Deleting flexible arrays

[smool]

I know the code too make new values, how do delete? i tried

var books : flexible array 1..4 of int
new books, lower (books) - 3

and it gives me an error

what kind of an error?

Also, what is the value of "lower (books) - 3"?

[smool]

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

Check the documentation of upper and lower
