Code / Description
Function IsArrayEqv(a1, a2) As Variant 'boolean
%REM
Compares two arrays to make sure they are equal.
Uses <> to make comparisons, so this function will not work with arrays of objects, arrays, or lists.
%END REM
Dim i As Long
Dim iLower1 As Long
Dim iUpper1 As Long
IsArrayEqv = False
If Not Isarray(a1) Or Not Isarray(a2) Then Exit Function
iUpper1 = Ubound(a1)
If iUpper1 <> Ubound(a2) Then Exit Function
iLower1 = Lbound(a1)
If iLower1 <> Lbound(a2) Then Exit Function
For i = iLower1 To iUpper1
If a1(i) <> a2(i) Then Exit Function

IsArrayEqv = True
End Function
Usage / Example
For a QuerySave event:
asNewFieldValues = Doc.FieldName
If Not IsArrayEqv(asOldFieldValues, asNewFieldValues) Then
Call UpdateDependentDocuments
asOldFieldValues = asNewFieldValues
End If
