Zugg Software :: View topic - [2.35] Variable = "" doesn't work as intended.

Posted: Sat Aug 09, 2008 4:36 am

I figured I'd clear out a variable and use variable="", but it no longer works.

1. #VAR testing {1|2|3}
2. #SAY @testing (It'll display 1|2|3)
3. testing=""
4. #SAY @testing (It'll display "")

Instead of clearing it out, it sets it to "" instead. Annoying indeed, because the next two steps create a slight problem.

5. #ADDITEM testing 1
6. #SAY @testing (It'll display |1)

As you can see, it counts the null as an item. There are two workarounds for this, though...

1. #VAR testing {} or #VAR testing ""
2. testing=%null()

It'd be nice if the old way worked again.

I've always used var=%null for this.

I never knew var="" ever worked.

Works fine for me.

Interesting...

On a related note and hoping this wouldn't derail this thread too much...

When you make a variable via PE, set it to String List and populate it with values, then on cmd line do "#va list %null" without the quotes

Then do "#va list", it shows it as a Autotype and not String List anymore.

Is this intentional?

That's completely normal. You should read the help file for variable.

#va list %null is the same thing as list=%null.

Fine. Until now though I believed that using %null clears the *content* of the variable, not the type of it. At least it seems reasonable for
it not to. I suppose I'll have to be more careful from now on under CMud when I use cmd line tactics such like this.
