Actually, if mycondition variable is not in scope at the time of the view creation, the view is not static. The macro will expand at execution time, so it will act like a parameterized view, i.e.

mycondition = [title = 'ABC']
use mydbc!myview
* all recs with title='ABC'

mycondition = [author = 'XYZ']
requery()
* all recs with title='ABC'
