You can do it because you have two monitors side by side and you can see half of the line on the first and the rest on the second ?

B4X:
Private Sub Button1_Click
Label1.Text = IIf(IsNumber(TextField1.Text) = False, "Invalid number", _
IIf(TextField1.Text > number, "My number is smaller", _
IIf(TextField1.Text < number, "My number is larger", "Well done!!!")))

Will this also be in the next release?
Yes. Beta version of B4J with these two features will be released today.
B4X:
Dim Index As Int = Sender.As(B4XView).TagBTW IIF too!!!
[for a small program that will make me a few thousand euros every month, even less than 10, perhaps ?]
P.S. IIF another time, right now:
B4X:
Dim Sign as int = IIf(EventData.PrimaryButtonPressed, 1, - 1)

I think B4X should make everything clear, logic and coherence would be better, especially for newbies, although it might have to write more commands.
I think B4X already is what you said except for the last part of your statement, which I don’t agree. B4X is the most not verbose programming language I ever see without compromising the easiness for beginners.
My first programming language is C in school, it took me so long to understand the for-loop. When I learn VB6 I love how simple it is to write a for-next loop. B4X shares the similar syntax and that’s what I like about the language.
C:
for (i=0; i<10; i++){
// do something
}
B4X:
For i = O to 9
'Do something

@Erel Just an observation I had while testing the BANano Tanspiler support for the new .As functionality:
Is Future a special case or is this because every Object can be converted to a String (e.g. for Logging)?
Here for example, I do get a correct warning #22, and even an expected Compile error:
Alwaysbusy
B4X:
' here I was expecting some kind of warning in the B4J compiler as I'm casting a Future (from GetCSS) to a String (I forgot the .Value after the GetCSS).
Log("JQAS: " & row2c1.As(JQueryElement).GetCSS("background-color").As(String).IndexOf("128"))Is Future a special case or is this because every Object can be converted to a String (e.g. for Logging)?
Here for example, I do get a correct warning #22, and even an expected Compile error:
B4X:
Dim jq As MyFirstClass
jq.Initialize("test")
Log(jq.mysecond.As(MyFirstClass)) '<-------- here I get a warning #22 because mysecond is of the type MySecondClass

Hola,Yes.
POLL: What do you use B4X for
I may participate if you added "for learning programming" option. Donewww.b4x.com
It is still true. For example, in HMG, users also contribute towards the development.
Si, y en el foro de ooHG también. Seguramente por que el espiritu del grupo es igual q B4X.
Saludos cordiales,
Sergio

Yes, and on the ooHG forum as well. Surely because the spirit of the group is equal to q B4X. Kind regards,
