Perry,
As long as the prg/proc/function/method/event etc is visible you can call it.
* Click code
1) You have a prg named myshutdown
myshutdown()
2) Your proc file has it
myshutdown()
3) Your custom class has a method
set classlib to myCustom additive
oProcs = createobject("myProcs")
oProcs.myshutdown()
4) Your form has the method
thisform.myShutdown

BUT, this is a shutdown procedure so be better not called from a button but from main proc after "read events".

*Main.prg
*Startup-setup code
read events && Start event processing

myCleanUp() && This would run after a "clear events" is seen
quit

function myCleanUp
...
