[RESOLVED] Using function name as return value

[DigiRev]

I've never done it like this, but I do see code that does pretty often. It seems like it would be bad practice, but also that it would be faster and not cause any problems.

Example:

'Example #1
Private Function GenerateString(ByVal Length As Long) As String
    
    Dim l As Long
    
    For l = 1 To Length
        GenerateString = GenerateString & Chr$(Int(Rnd * 255) + 1)
    Next l
    
End Function
 
'Example #2
Private Function GenerateString(ByVal Length As Long) As String
    
    Dim l As Long
    
    GenerateString = Space$(Length)
    
    For l = 1 To Length
        Mid$(GenerateString, l, 1) = Chr$(Int(Rnd * 255) + 1)
    Next l
    
End Function

vs.

Private Function GenerateString(ByVal Length As Long) As String
    
    Dim l As Long, strReturn As String
    
    For l = 1 To Length
        strReturn = strReturn & Chr$(Int(Rnd * 255) + 1)
    Next l
    
    GenerateString = strReturn
    
End Function
