Replicator code.

If _Test <> 0 Then
     ;
EndIf
 
Func _Test()
     MsgBox(16, "", "")
EndFunc

Console output

Notice I left out the parenthesis on "_Test()"? Shouldn't this throw a compiler or syntax error? It doesn't on my build.

Thank you guys for all your time and for being patient. I know I've been asking a few annoying questions lately.

Why do you thing there's an error? What error you expected?

[BinaryBrother]

It doesn't actually call the function. Let me give a better example. It took me a little while to find an error in my code because of this. Is this not technically bad syntax? This is why I like bringing things to chat, before posting bug reports. I could be wrong; I probably am.

 

If _Test = 0 Then
     ConsoleWrite("Returned correctly.")
Else
     ConsoleWrite(_Test2) ;Nothing
EndIf
 
Func _Test()
     Return 0
EndFunc
 
Func _Test2()
     Return "Hello"
EndFunc

I am expecting a compiler error to say "Bad Syntax, you forgot parenthesis!"

Then this code will surprise you when you run it:

$vPrintFunc = ConsoleWrite

$vPrintFunc("WTF!" & @CRLF)

Anyway, search around the forum (and internet) for term "first class".

Oh snap! That's a very interesting development!

Edit: Alright, I'm back after reading a while on it. This is some pretty interesting stuff. I'm surprised to see it was actually implemented some time ago. I think I remember reading about it before but had forgotten about it. No matter how long I stare at that example you gave me, I just can't wrap my head around it. I see a multitude of new possibilities, I think.

Do you have a few practical examples that you could point out - right off the top of your head? If not, don't worry about it. I'll do some digging as time permits.

Thanks for the information trancexx. As always, you have my gratitude for being informative and patient.

BinaryBrother,

 

Do you have a few practical examples that you could point out

Look at the code in this post - a function is assigned to the $hType variable which is then passed to a function as a parameter ($hDataType) for use within the function.

Edit: That code has now been removed. Look at the example for _ArrayDisplay in the latest Beta which shows the same thing - a function is assigned to the $hUserFunction variable which is then passed to the function as a parameter for use within it:

; Assign the user function to a variable to pass as a parameter
Local $hUserFunction = _UserFunc

$aArray_2D[5][5] = "Column alignment set to right"
_ArrayDisplay($aArray_2D, "Range set - right align - copy column width - user function", "3:7|4:9", 2, 15, "AA|BB|CC|DD|EE|FF", Default, Default, $hUserFunction)
