Logical NOT Operator (' ! ') in If-statements.

[Dude]

On the flip side this should not work either:

Code: Select all

a.s = ""
b.s = "abc"
If a : Debug "a" : EndIf
If b : Debug "b" : EndIf

But it does.

Well, it only shows "b" in the Debug Output for me. So, it works correct here.

Same observation and opinion as I had came up with earlier when having seen that.

Code: Select all

a.s 
b.s = ""
c.s = "abc" 

If @a : Debug "a is set" : EndIf
If @b : Debug "b is set" : EndIf  
If @c : Debug "c is set" : EndIf  

If Not @a : Debug "a not set" : EndIf
If Not @b : Debug "b not set" : EndIf
If Not @c : Debug "c not set" : EndIf  

m@kes sense doesn't it?

It does m@kes sense LOL.

it works but I'm not sure if it makes sense, I'm away in the Land of Grey and Pink

With a.s your declaring a variable type.

With the usage of @ in the If-statement for the a variable, it's returning zero because there's no address until it's set.

With b variable and just specifying "", now variable has been set and address exists, no longer returning 0.

The Not operator works because it's going by addresses, hence numeric and not string.

... you know all this. Why wouldn't this make sense?

you missed the part, I'm away in the Land of Grey and Pink. otherwise it m@kes sense!

I'm not wanting what you having... There's lot already that doesn't make sense to me, don't need the enhancements.

And later will you be standing on a golf course, dressed in PVC?

That's boolean on strings - so NOT should work too.

Technically if (If a$) is allowed (If Not a$) should be allowed too.
