You should delete this code and use ResumableSubs: [B4X] Resumable subs that return values (ResumableSub)

Hello, thank you.
And for cases where a "Sub" returns at different points of another "Sub", what should be used?
Example:

B4X:

sub aaa
  wait for (bbb("hello") complete (result as object)
  continue doing something
end sub

sub bbb( zzz as string )
  some code
  return null
  '
  other code
  return null
  '
  some other code
  return null
  '
  And finally
  return null
end sub

Everything you need is explained in that tutorial. It doesn't matter where or how many times you return from the called sub.

Sorry, I was just trying to confirm what I understood by watching the video tutorial.
It's just that my knowledge of English is not enough to understand the narration you do, I could only follow the video.
Thank you.

Hi vecino:

Maybe if you explain what you're trying to do with your real code, then it will be easier to help you.

Hi, it works fine with "ResumableSub" and "Return Null" when it is not necessary to return anything.
Thank you.
