Hello!
I have a simple question.
After using Input query and pressing OK, or something like this,
the InputQuery form closes.
Is it possible that the for still stays open,
in this way another Input can be provided.
Thanks in advance.

This is not so simple..

No, The InputQuery Dialog is a modal window and gives the input back when the user clicks OK.
After the OK the modal window closes and you can catch the value in your code.

You can try to loop and (re)display the Dialog

repeat
    if not inputquery('Test program', 'Please type your name', value) //Because the Dialog is executed as Modal your code stops/waits here..
    then ShowMessage('User cancelled the dialog');
  until value <> '';


If you want to catch more inputs from the dialog without closing it then you need to
create a dialog that is opened it with "Show" instead of "ShowModal"
But because your source will not stop/waiting for closing you need other techniques
to pass the input back to your main window. (like a callback function)
