//	This function enables the autotab feature of the forms. When called by the onkeyup event handler for a
//	form control, this function transfers the control to the next control, similar to pressing TAB key.
//	e.g. onkeyup="autoTab(this,9,event,null)"
//	input 	- 	form control object (pass as: this)
//	length	-	length at which autotab will occur
//	e		-	event object (pass as: event)
//	any		-	any other object that you want to pass control to, instead of next. Otherwise pass as: null
