I believe that at one time you mentioned the possibility of extending an enumerated type. This would greatly facilitate object oriented programming. For instance, I have created a Person_Names package. The components of the name are contained in a record. The tile part: Mr, Ms, Miss, Mrs, Dr, Prof, etc. must include other. If one needs to make Person_Names.Military one has to add the ranks. For Person_Names.Clergy, we go from Priest, Rabbi to Pope. I most strongly believe that although enumerated types are extremely useful, it is in some cases impossible to anticipate all of them. Extending enumerated types in child libraries would permit object oriented programming with this construct. I will be unable to participate in any discussion until Jan 26, 2001. I have to Chair a session on Advanced Techniques in Analytical Cytology at SPIE BiOS 2001. Unfortunately, I think that I am the only one who uses the word Ada at this SPIE meeting. Many of the devices reported upon can be life-critical. The level of software development is often quite depressing. -----Original Message----- From: comp.lang.ada-admin@ada.eu.org [mailto:comp.lang.ada-admin@ada.eu.org]On Behalf Of Tucker Taft Sent: Friday, January 19, 2001 2:51 PM To: comp.lang.ada@ada.eu.org Subject: Re: When will next Ada revision be?
