Timely response - awesome! I’ll be checking this in the morning, as I’m about to head to sleep xD.
The do {} while(0) is literally nothing more than habit: I tend to add that in all of my macro “functions” to eliminate scoping issues and keep things contained. The only exception to this rule is with one liners and such. It’s not an uncommon practice - actually highly recommended 
Thanks again for the help. Take care!
