Reads the mouse event queue and returns information about an event.
  
 
	  
		Note: This routine is supported for native COBOL only.
		
 
 
	  
 
	 Syntax:
 
		 
		call "CBL_READ_MOUSE_EVENT" using     mouse-handle
                                      event-data
                                      read-type
                            returning status-code
 
	 Parameters:
 
		 
		 
		
 
			  
			  
			  
			  
				 
				  |  | Using call prototype (see 
					 Key) | Picture |

	 On Entry:
 
		 
		 
		   
			 -  
				mouse-handle 
			 
- Mouse identifier, obtained by earlier call to CBL_INIT_MOUSE. 
			 
 
		   
			 -  
				read-type 
			 
- Indicates what to do if there are no events in the queue: 
				
 
					  
					  
					  
						 
						  | 0 | Return immediately |   
						  | 1 | Wait for an event and then return |  
 
Comments:
If there are no events in the event queue, the return from this routine depends on the value of read-type. If read-type is zero, the routine returns immediately with all zero values in event-data. If read-type has a value of one, return is delayed until an event has been queued.
The CBL_ mouse routines do not work with the x"AF" mouse routines.
