The use of Option Base to change the lower bound of an array’s index values results in confusing code.
Noncompliant code example
Option Explicit
Option Base 1
'...
Dim MyArray(1 To 3) As Integer
For I = 1 To 3
MsgBox MyArray(I)
Next I
Compliant solution
Option Explicit
'...
Dim MyArray(0 To 2) As Integer
For I = 0 To 2
MsgBox MyArray(I)
Next I
