Pardon my ignorance, but can this be done? Thank you for your time.

A()

Function A()
B(C)
End Function
'
Function B(ptr)
ptr()
End Function
'
Function C()
End Function

function pointers?

A() 

'
Function A()
	B(C)
End Function
'
Function B(call())
	call()
End Function
'
Function C()
Print "ok"
End Function

That seemed to do the trick! Thanks!! :) :) Now here's one for ya... ;)

Q) What's the best way to get a random object from a TList?

ListObject.ValueAtIndex( rand( ListObject.Count() - 1 ) )

Oh dear god...that was too obvious, thanks!. And also thanks SOS for proving how much of a BlitzMax noob I am. :) :)

Well, here we grow again... :)

When the Graphics() function fails, what's the best method to visually tell the user there was a problem? Since there's no screen available, how do we display information to them? Thanks.

Notify :-)

Hey you should buy my framework, then you won't have to write one, you'd have saved tons of time already ;-) kidding I know you want to write one for fun (or something)

I tend to use notify.

Notify("There was a problem initializing video mode. Please update your videocard drivers and try again.")

Thanks!! eek!! Ok, jeesh...another easy solution. Phew!! :) :) :)
GA - Your idea and my idea of framework is totally different. lol.. Your's is a complete robust (impressive) "solution", MGE will not be a framework, more like a took kit you can plug in any app. They should (knock on wood) work wonderfully together. ;) At this point if I was to buy a framework it would save me perhaps months of coding, but I wouldn't come out any smarter. doh! ;)

for sure writing a framework is a great learning exercise and at the end you have something useful :-)
