Problem description: A missing optional argument is treated as a not declared
variable.
Steps to reproduce:
See a code example below.
--------------------
Option Explicit
Private Sub Do__Error__Optional_argument_is_not_a_variable__Error(Optional
ByVal anArgument)
Dim aVariable as Single
If False Then Dim anArgument as Boolean
aVariable=anArgument ' This line produces an error 12, if "option
explicit' is used.
aVariable=-456 ' This line is executed only if "option
explicit' is NOT used.
End Sub 'Do__Error__Optional_argument_is_not_a_variable__Error
Private Sub Do__Error__Optional_argument_is_not_a_variable__Success(Optional
ByVal anArgument)
Dim aVariable as Single
'If False Then Dim anArgument as Boolean
aVariable=anArgument
aVariable=-456
End Sub 'Do__Error__Optional_argument_is_not_a_variable__Success
Sub Error__Optional_argument_is_not_a_variable
Do__Error__Optional_argument_is_not_a_variable__Success anArgument:=-123
' This call never produces an error.
MsgBox "1: +"
Do__Error__Optional_argument_is_not_a_variable__Error anArgument:=-123 '
This call produces an error 12, if "option explicit' is used.
MsgBox "2: +"
