Thanks for this. I hadn’t found the switch statement but thats clearly a better way to do it (you were far too polite to my original idea).
Am not next to machine at the moment, but will program that in when back later this morning.
That also has the advantage of not requiring two macro groups, is all encoded in one place and is self documenting, I use C and Perl so anything is self documenting compared to C and Perl 
I’m still getting my head around what to use the Falcom-8 for. I’m so used to a simple keyboard that having additional keys seems odd. However the concept of application sensitive keys seems really good.
I’ll report back so other people can take advantage of any macros I write (to at least the framework).
