No, +E/R, +Init and +Set are all different. +E/R is bi-directional, it sets the GUI from the DB, and writes back changes. +Init runs only once, during the HTTP GET transaction (i.e. not at POST transactions when a button was pressed). +Set is triggered whenever a value is *written to* the GUI (as opposed to +Val which triggers when a value is *fetched* from the GUI. Your combination of +Init and +Set means that when the page is loaded, the value is written immediately back to the DB, which is not nevessary. Such a side effect is better done in +Val (though +E/R does that better). ☺/ A!ex -- UNSUBSCRIBE: mailto:picolisp@software-lab.de?subject=Unsubscribe
