What is the purpose of the colon?
e. g.:
Dim objConn : Set objConn = OpenConnection()`
Is the colon used to combine the two statements into one line? I just want to be sure.
P.S.: I tried searching the answer to this question on Google with no luck.
回答1:
Yes, the code would work exactly the same on two lines; the colon's just a statement separator.
回答2:
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.
回答3:
Yes this is correct. In VB style languages, including VBScript, the colon is an end of statement token. It allows you to place several statements on the same line.
回答4:
What you have stated is correct. The purpose of the colon is to combine 2 otherwise separate lines into a single line. It works on most statements, but not all.
