The following tape labeling scheme has been adapted:
A tape label consists of three fields, separated by two ``.'' (dots),
e.g. xyz.a.b
The first number (xyz) is an index, that has been set arbitrarily at 10,000
at the beginning of the data taking in the 1994 run. NOTE: This number is NOT
the run number. It is a consecutive index for the physical tapes, each of
which can have several runs on it. The other two numbers (a,b) are indices
for the multistreaming. a is the number of tapes to which data was
simultanously written to, the other an index (1 
b 
a). If there
is only one tape as output device, then a = b = 1. Output to disk or
trashcan has of course no tape label.
The dp0 user interface does NOT accept labels in any other format.
