: b has been dimmed, but it doesn't have a value yet when the code is
: compiled. It doesn't get a value (b=10) until after all the compiling has
: finished. Part of the compiling process, as I believe, is making room in
: memory for the variables (dim). That, and checking for unterminated
: strings, syntax errors, etc. So, if you're the script interpreter, you'd
go
: to declare an array in memory and see that you should make room for "b"
: elements. But you do not know what b is, as you have not yet gotten to
the
: point at which you start reading lines like "b=10." I guess you could
: parallel this logic with why you cannot do <!-- #include
: file="<%varName%>" -->. That's a different thing, of course, but the
logic
: behind why you cannot do it is the same, if that helps at all.
Yes, this with your other post that Dim is compile-time and ReDim is
run-time makes sense.
