Logical Operators¶

Logical operators work on Boolean expressions and yield Boolean results.

Operator	Description	Example	Result
`And`	Logical AND	`True And False`	`False`
`Or`	Logical OR	`True Or False`	`True`
`Not`	Logical NOT	`Not True`	`False`
`Xor`	Logical XOR	`True Xor True`	`False`

Dim a As Boolean = True
Dim b As Boolean = False
If a And Not b Then
  Print("a is True and b is False")
End If

Dim a As Boolean = True
Dim b As Boolean = False
Dim c As Boolean = a And b   // False
Dim d As Boolean = a Xor b   // True

Multi‑Dimensional

Dim grid(2, 2) As String        // 3×3 array

Re‑Dimensioning
ReDim arr(n) resets size (contents lost)
Bounds
Use array.LastIndex to query highest upper index.

Dim names() As String
ReDim names(2)                   // indices 0–2
names(0) = "Alice"
names(1) = "Bob"
names(2) = "Carol"

For i As Integer = 0 To names.LastIndex
  Print(names(i))
