FB utilizes Apple toolboxes to create, manipulate and dispose of all windows, controls and edit fields. For example, toolbox calls, even though hidden, are at the core of Appearance window and appearance button statements. I'm not aware of another method that makes sense. Apple's calls are succinct and proven, so there is no reason to write our own window / control creation code. > all the old 680XX assembler knowledge would be useless now that > we're on Intel chips. I haven't written or seen 680xx assembler for at least 20 years. PowerPC assembler, which replaced the 680xx, disappeared with the introduction of Intel machines 3 years ago. Brian S.
