A task which is started by typing RUN taskname may be aborted
	by typing 
			ABORT
 
	If one wishes to abort an installed task(ie one which is started
	by just typing a 3 character name, ie PIP)  type 
			ABORT taskname
 
	If a task has a file open when it is aborted, the file will be
	LOCKED.  The file must be UNLOCKED with PIP before it can be
	used again.  For information on unlocking files, type
