Dave, One of the first big 4D projects I took on was interfacing 4D with an OS/2 based POS system. From that I tinkered with the idea of writing one for a while. It's certainly doable and I'm sure some enterprising Devs have accomplished it. That said I would suggest you look at whatever task you need to accomplish from a results oriented perspective.
If the requirements are pretty low volume and you anticipate them staying that way you may want to roll your own POS to accommodate. If the expectation or current need is fairly robust then the POS system needs to be more than a bolt-on solution. In this case I'd look at existing solutions with an eye toward the best fit for the client AND ease of interfacing with the 4D app. POS is one of those things that in theory is pretty straightforward but it is a massive crate of devilish details with added benefit of needing to interface with various flavors of hardware and payment processing. What fun! Throw in a smattering of accounting, user training and so on and it just gets better and better. Like I say, if the scope of your needs are narrow you may be better off doing your own. Otherwise let a POS company worry with that stuff and concentrate on how to get your database to pull the good parts out of their system. To return to my opening story that is exactly what my database did. It pulled a daily data dump from the POS system and converted this into data we were using. This was a restaurant so we wanted menu analysis, bar inventory, accounting, and so on. There was a similar process for the time clock (different system back then) and all those data were aggregated for payroll, accounting and management. Pretty cool for the late '80s.
