### Or (operator)

 Syntax expression1 Or expression2 Description Performs a logical or binary disjunction on two expressions. Comments If both expressions are either Boolean, Boolean variants, or Null variants, then a logical disjunction is performed as follows: If the first expresionn is and the second expression is then: the result is TRUE TRUE TRUE TRUE FALSE TRUE TRUE NULL TRUE FALSE TRUE TRUE FALSE FALSE FALSE FALSE NULL NULL NULL TRUE TRUE NULL FALSE NULL NULL NULL NULL Binary Disjunction If the two expressions are Integer, then a binary disjunction is performed, returning an Integer result. All other numeric types (including Empty variants) are converted to Long and a binary disjunction is then performed, returning a Long result. Binary disjunction forms a new value based on a bit-by-bit comparison of the binary representations of the two expressions according to the following table: 1 Or 1 = 1 Example 0 Or 1 = 1 5  10101001 1 Or 0 = 1 6  01101010 0 Or 0 = 0 Or  11101011 Example 1 This first example shows the use of logical Or. Sub Main()   temperature_alert = True   pressure_alert = False   If temperature_alert Or pressure_alert Then     MsgBox "You had better run!",ebExclamation,"Nuclear Disaster Imminent"   End If End Sub Example 2 This second example shows the use of binary Or. Sub Main()   Dim w As Integer TryAgain:   s\$ = InputBox("Enter a hex number (four digits max).","Binary Or Example")   If Mid(s\$,1,1) <> "&" Then     s\$ = "&H" & s\$   End If   If Not IsNumeric(s\$) Then Goto TryAgain   w = Cint(s\$)   MsgBox "Your number is &H" & Hex(w)   w = w Or &H8000   MsgBox "Your number with the high bit set is &H" & Hex(w) End Sub See Also Operator Precedence (topic); Xor (operator); Eqv (operator); Imp (operator); And (operator).
