Message-ID: <1993Aug9.015830.2453@sifon.cc.mcgill.ca> (raw)

	    

Does ADA ( 8x or 9x ) have procedure variables or similar ?
Does ADA ( 8x or 9x ) have type extension or similar ?	
  
TYPE	
	BaseType = RECORD  
		x,y : INTEGER;
	END;	   
		    
	ExtendedType = RECORD ( BaseType )       
		z : INTEGER;
	END; (* an extension of BaseType with fields x,y,z *)
	
	Handler = PROCEDURE ( VAR msg : BaseType ); (* PROCEDURE TYPE *)
	
VAR 
	handler : Handler; (* procedure variable *)
	
									
	
Thanks,
	Whitney
