[thelist] ASP Problems again..

[Jerry Scannell]

VB Script will give you an error if you use parantheses when calling a "sub"
since subs don't return anything.  Conversely, if you omit () on function
calls, you will also get an error.

It is a good idea to always write your own routines as functions so you can
return something, even if it is 1.  then you can utilize the () which are
required in practically every other programming language (e.g. c, fortran,
etc.)
