There are a lot of theological arguments about what is or is not an object-oriented language. The basic idea is that objects send messages to other objects, and that some message delay the sending object until the receiver sneds a response, will other messages allow the sender to run asynchronously with the receiving object. Methodfs are built on top of that.

The ooRexx documentation has a lot to say about messaging, which is a bit confusing to me because I first got a handle on OOP in VBA and VBSCript, which do not. If the big idea is messaging, does VBA do that and I just didn't notice? Or are the VB flavors something different that don't do messaging, or not very much? --- Bob Bridges, [email protected], cell 336 382-7313 /* It is in vain to say that democracy is less vain, less proud, less selfish, less ambitious, or less avaricious than aristocracy or monarchy....When clear prospects are opened before vanity, pride, avarice, or ambition, for their easy gratification, it is hard for the most considerate philosophers and the most conscientious moralists to resist the temptation.

Flatscher Sent: Saturday, July 2, 2022 15:05 Alan Kay is regarded to have coined the term "object-oriented programming (OOP)" in the context of his work while at PARC. He is being cited on Wikipedia: I'm sorry that I long ago coined the term "objects" for this topic because it gets many people to focus on the lesser idea. The big idea is "messaging".[8] Cf. <https://secure-web.cisco.com/1M2FMmo9KD7XBMhnhVNEqL_PCk_U2u-opXfiaRy4Bpo2SxWbPs-4000_Jyqe2uRLB_ptvUbRhYHtW6p7c8NbowQwdeUJ3nP193MZR6NvBuQ6SCzw11qfV5VNBbxuTXm1QidA59kvD8te387l4aGm29IeuIo8lDT4tvrTq1q7HfAhMgVh1UsA7rq6cANNrKdxbiBk-3JXibY6ooouWsg7F5UDnC-FqhqlSBqpJIqe2Fx7SZ5q_fqvg87epYOPJARM9TG3Hd77Zf7PjrNR9g2H1lhOCsvdAZT2kD51Hkrmok7Y6_3s-z4dsu4ZqHTgNjVoL1MFp-0wBPqAOWz1usLCyeVTKmzogj5DHtx2EdPYh4CogBVDxQrtmq_jSRylVLh6LVOn9rz3tPRVSHxzx6aj6Jxwl3uRMNfZXoFjsZcTtNYsoR9Fsq29V97WCfpJWKvGI/https%3A%2F%2Fen.wikipedia.org%2Fwiki%2FAlan_Kay%23cite_ref-8>. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
