Speed/Efficiency for If-Else Construct

Hello,

My question is about the If-Else Construct.

I often write If-Else statements that require an action be taken only if something is true. If that something is false, no action is to be taken.

My question is, how do you code "no action".

The following is what i usually code:

As you see above, when false, I usually just assign the variable the value it already has. That's because I want nothing to happen if the result is false.

But isn't that a waste of time for my program? Am i not just giving my processor one more thing to do for no reason. Slowing down my program with unnecessary assignments?

If so, what are my alternatives? Is there a common programming strategy that all programmers adhere to in this situation? I mean, do I just put nothing after the Else Construct (except for a maybe a comment noting the nothingness was intentional)? Hmmm...

Thanks for any help! Trying to be efficient here

If no Else is required you can use one line, eg:

No Else/End If required

Another alternative to the above in this context:

An Else is not a pre-requisite of an If construct, eg:

Sometimes you will see people code multiple lines on one line using a colon delimiter, eg:

The latter can be useful if condensing code into as few a lines as possible but generally speaking it's much harder to debug so is not adopted very often.
