= <span class="f_Header">Remarks</span> =

By default the first element of an array starts at 1. With CONFIG BASE=0 you can override this default so that all arrays start at 0.

In some cases it is simpler that elements start at 0.

A constant named _BASE reflects the setting. You can not change the BASE at run time.

&nbsp;

[[File:Notice.jpg|left|Notice.jpg]]When you change this setting in existing code, you need to alter your code. For example when you used this code:

Dim a(10) as byte&nbsp;: a(10) = 10

And you set CONFIG BASE=0, it will mean that element 10 is invalid.

&nbsp;

While in QB an additional element is created, this is not a good idea in bascom because it will require more space.
