Yes. The Pub.Win32 module contains LoadLibraryA and GetProcAddress functions which you can use to load DLLs and get pointers to the functions contained in them.

I managed to get it working using this code, but it is very messy - there must be a much easier way to convert Byte Ptrs to the appropriate type of function pointer.

main

Function main()
	Local MessageBox(hWnd,text$z,caption$z,id)
	
	modHandle=LoadLibraryA("User32")
	If modHandle
		Local q:Int Ptr=Int Ptr(GetProcAddress(modHandle,"MessageBoxA"))
		'Really, really ugly and error prone - not a good idea!
		Local p:Int Ptr=Int Ptr(Varptr MessageBox)
	
		p[0]=Int(q)
		
		MessageBox(0,"HELLO WORLD","HI!",0)
	EndIf
	
	
End Function


Please don't use this to break multiplatform support though ;)
