A pattern match is a reasonable method. I use pattern matching more often 
that the read() application. Try both and see which meets your needs 

Are you really defining a 'macro' or is that just the (misleading) name 
you chose for your context. Personally, I use gosub() more, but again, 
try both :)

I suggest you try 'dialplan show macro-age' to see how Asterisk is 
interpreting your dialplan. I suspect it is not what you expect.

In specific, your ordering of '_xx' in the middle of 's' is odd. This 
would disrupt the value of the priority in older versions of Asterisk, but 
it appears that it does work in modern (I'm using 11) versions.

Also, a label ('notEmpty') belongs to a priority, not an extension.
