I'd say the big issue prior to VB10 is multi statement lambdas.

As for my case, we (the company I work for) have an app residing on a VIA EPIA mini-ITX card. That is the bottom reason for my earlier statement that I dislike dotnet. This doesn't mean that I'm against dotnet itself, but the guy that wrote addons to our C++ app in VB dotnet didn't make me a fan. We just can't afford to let dotnet in to our resource-restricted hw. I also started to test if we can run XPEmbedded, since XP is no longer available. Maybe you can explain to me what Scott is talking about when comparing VB6 to dotnet would make me a better VB6 coder. /Henning

What's your point in showing it here? 90 L=1 100 FOR J=1 TO 13 110 E=0 The point was that in older BASIC (even older than this sample), Let was required for variable assignment, it should have been: 90 Let L=1 100 FOR J=1 TO 13 110 Let E=0 VB6 still supports that (test it): Dim A As String Let A = "AA" Debug.Print A It's not required at all, but still supported. And the point was that in 1982 BASIC's, it was already optional. The Property Let Statement is another matter. There Let is required, but it wasn't what they were talking about.
