Nested If statements

[Denis]

It works neither in this form:

SetError(0)

FileReadLine($File1)

If @error Then

SetError(0)

FileReadLine($File2)

If @error Then FinalMessage("Equal")

Else FinalMessage("Not equal - 2 is longer")

EndIf

FinalMessage("Not equal - 1 is longer")

nor in this:

SetError(0)

FileReadLine($File1)

If @error Then

SetError(0)

FileReadLine($File2)

If @error Then FinalMessage("Equal")

EndIf

Else FinalMessage("Not equal - 2 is longer")

EndIf

FinalMessage("Not equal - 1 is longer")

nor in this one:

SetError(0)

FileReadLine($File1)

If @error Then

SetError(0)

FileReadLine($File2)

If @error Then

FinalMessage("Equal")

else

EndIf

Else FinalMessage("Not equal - 2 is longer")

EndIf

FinalMessage("Not equal - 1 is longer")

It works as this:

SetError(0)

FileReadLine($File1)

If @error Then

SetError(0)

FileReadLine($File2)

If @error Then

FinalMessage("Equal")

Else FinalMessage("Not equal - 2 is longer")

EndIf

EndIf

FinalMessage("Not equal - 1 is longer")

but I still don't like the entire matter - it may occur again in much worse state.

//Func FinalMessage (Const $MessageName)

// MsgBox(0,$MessageName,TimerDiff($timerstart))

// WinWait($MessageName)

// Exit

//EndFunc

The first one should look like this:

If @error Then
    SetError(0)
    FileReadLine($File2)
    If @error Then
        FinalMessage ("Equal")
    Else
        FinalMessage ("Not equal - 2 is longer")
    EndIf
EndIf
FinalMessage ("Not equal - 1 is longer")

You cannot add code on the same line after the Else keyword.
