I am not quite sure what you mean by the "Vienna telephone Directory", but if you mean the Vienna Parkrink VDL formalization of PL/I, you will find a full treatment of breakoff in it.
Parkrink? Did you mean Parkring, the street dividing the first and third district (Bezirk) in Vienna?
<OT> Starting in the 1860s, the fortifications around the first district, that didn't completely protect Vienna, were removed. The freed space was used for a wide road, Ringstrasse, and civic buildings (city hall, university, museums of art and natural history, theater, etc.) were erected over the next twenty years). The fortifications around the outer districts were removed and replaced by a wide road, Gürtel, later split by an elevated streetcar line. Also the Wien and Danube rivers were placed into dedicated channels, a canal was built through Vienna (originally for sanitation), and a recreation area was built on the east side of the Danube, doubling as an area to contain overflow during times of high water (which failed a few times last century). </OT>
For the readers who are confused, a nice VDL paper appeared in the IBM Journal of Research and Development:
