Thank you John -- that is most kind. I feel encouraged !

Yes, same here. I started with MS-DOS 1.1. Batch programming isn't really my "thing" though -- I prefer more strongly typed and structured languages like C. I only learned batch programming out of necessity when doing network admin., etc.

Yes, agreed.

That's what makes this forum so excellent -- we can all learn from each other. The forum dynamics have changed as ZTreeWin has matured, but I really, really hope it keeps going.

Thanks again John.

PS: I've just realised that you live in Orlando. I hope all is well with you, after Hurricane Irma. I was very relieved to see its path veer off to the west of the Florida peninsula -- I bet Tampa was hit hard, though.
