That would work, but can causes problems if you have concurrent calls as 
you are using a global variable.

I think you can also workaround by using variable inheritance, e.g:

; use _ for one-time inheritance
Set(_Digit=123)
; use __ for infinite inheritance
Set(__Digit=123)


In both cases you query the value as before without underscore, e.g.:

NoOp(${Digit})
