// - MyProcedure
// - MyProcedureCalledAfter
p()
Windows
// Specifies the process to run on a click
BTN_BUTTON1..Process[trtClick] = myProcedure1

// Adds a procedure to run on a click
BTN_BUTTON1..Process[trtClick] += myProcedure2

// Adds a procedure to run after the click process
BTN_BUTTON1..Process[trtClick]..After += myProcedure3

Exiting from the sequence of procedures

If several procedures are sequenced, the sequence of procedures can be interrupted from the code of one of the procedures by using ReturnToCapture.
Example:
// Click on BTN_Button1
BTN_Button2..Process[trtClick]..After += MyProc1
BTN_Button2..Process[trtClick]..After += MyProc2
// Click on BTN_Button2
Trace("Button 2 clicked")
PROCEDURE MyProc1()
Trace(dbgInfo(dbgProcess))
ReturnToCapture(MySelf..Name)
PROCEDURE MyProc2()
Trace(dbgInfo(dbgProcess))
