how to extract this data

[scila1996]

I have a program

#include <GUIConstants.au3>

#Region ### START Koda GUI section ### Form=
$Form1 = GUICreate("AForm1", 233, 174, 193, 115)
$Input1 = GUICtrlCreateInput("1996", 88, 24, 33, 21, BitOR($ES_UPPERCASE,$ES_LOWERCASE,$ES_AUTOHSCROLL,$ES_NOHIDESEL,$ES_OEMCONVERT,$ES_WANTRETURN,$ES_NUMBER))
GUICtrlSetLimit(-1,4)
$Button1 = GUICtrlCreateButton("AButton1", 72, 88, 75, 25, 0)
GUISetState(@SW_SHOW)
#EndRegion ### END Koda GUI section ###

While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $GUI_EVENT_CLOSE
            Exit
        Case $Button1
            $tentroll = GUICtrlRead($Input1)
            MsgBox(0,"FB Troll",$tentroll, "",$Form1)
    EndSwitch
WEnd

for example 

 

- If I enter the number in 1885, while pressing the button will display the last digit of the number 1885 = 5 

 

---> Made the announcement about the end of the 4-digit number on 

 

Can you help me, I thank

Thank you. I did succeed 

 

I just started learning to program and from AutoIt, my English is weak, you should expect help 

 

Thank you
