[SOLVED] How to call procedure

Let say I have a GUI with a button named $bt_process.

Case $bt_process

        ; do many things there

        ; could be consist of many lines

Let say I have a InputBox on the same window.

I want if user input "AAA" then do above procedure just like when he click on the $bt_process button

If try this without result:

If GUICtrlRead($inputbox1) = "AAA" then

    $bt_process

Endif
