VBScript, purpose of colon?

Question

What is the purpose of the colon?

e. g.:

Dim objConn : Set objConn = OpenConnection()`

Is the colon used to combine the two statements

Answer 1

You can put two (or more) lines of code in one line. It's most often used, as in your example, to declare and set a variable on one line.

Think of it like a semicolon in every other language, except optional.
