Hi, @joe-mccay, @coises, @mark-olson, @mkupper and All,
Ah… yes, the @mkupper’s formulation of the search regex is very clever and quite clear, thanks to the free-spacing mode !
I particularly like :
The (?:,((?1)))? syntax, where you join the optional states of, both, the (?1) form and the comma
The use of the leading i modifier to simplify the group 1 syntax
Bravo !!
BR
