[jawsscripts] SendMessage function?

Does anyone know where I can get a list or where there is a reference guide to use the SendMessage function? This appears to be a Windows command, and JAWS documentation about it, simply states that the user should consult a programming manual... Whichever that is...
For instance, the following usage will maximize the current application window. 

Script MaximizeCurrentAppWindow()
var int Rslt

SendMessage (GetAppMainWindow (GetFocus ()), 274, 61488, Rslt)

EndScript
I have no idea how to find the numerical values that cause this to happen though, or what exactly they mean.
Does anyone know anything about this capability? Or where I could learn more? 



Thanks,



Bryan
