Declare variables in own subroutine

[dancer]

Using ASP.net 1.1 and VB

Is it possible to declare variables in their own subroutine?

I had my DIM statements within a sub that worked just fine.
I wanted to be able to use them in another sub, so I isolated them in their
own subroutine.
But when I call that subroutine within another sub and then try to use those
variables, it does not remember that they have been declared. I get the
message, "Name is not declared."

When I have those same variables declared in the exact same way WITHIN the
second sub it works fine.

If you want a variable to be accessible from multiple routines, you'll
either have to declare the variable at a higher level, or do something like
passing it ByRef. If you can provide a trivial example of what you're doing
and trying to accomplish, even generically, it will probably be a lot easier
to get you from point A to point B.

When you declare variables inside a method, they are local to the
method. The memory for the variable is allocated on the stack when the
method is called, and the stack pointer is restored when the method
ends, so the variables doesn't exist in any way outside the method.

Should I declare the variables again in each subroutine I want to use them
in?
There are 59 variables.

Thanks

That depends on what you want to do.

If you declare two variables with the same name in separate methods,
they are separate variables and have nothing to do with each other. If
you want to use the variables to share data between methods, you have to
declare them as members in a class.

How do I "declare them as members in a class"?
I tried declaring them outside my subroutines, thinking they would be
global. But the subroutine still did not recognize them.
