Hi :) Sorry about my replies to this idea of using macros! i don't use nor understand macros at all. From what people have been saying to me off-list it sounds like they are much more efficient than i had assumed. Plus it sounds like there is some scope for building a whole proper app that way. It sounds well worth exploring! :)
Anyway, many apols and regards from Tom :) On 7 May 2014 10:17, Tom Davies <tomc...@gmail.com> wrote: > Hi :) > Macros are code running on a desktop machine right? So don't they take up > cpu cycles?
