Hi,
Hah, I knew it when the Wend came up!

Paul,
But of course, While Wend went out with the
Commodore-64 and has been deprecated for a couple
decades, and should never have appeared in
E-Basic at all (see my comments at
https://groups.google.com/d/topic/e-prime/JXcYIfRPWVE
and www.pstnet.com/forum/Topic3215-9-1.aspx
). What if you use the more modern Do Loop? E.g.,
Dim n As Integer
Do While False
n = 1
Loop
I don't have any sympathy for crashes that result from use of While Wend :).
Regards,
