I agree that the error message is confusing. First, the F2008
constraint is
C1006 (R1008) w shall be zero or positive for the I, B, O, Z, F,
and G edit descriptors. w shall be positive for all other
edit descriptors.
Second, we have
10.8.5 P editing
The k P edit descriptor temporarily changes (9.5.2) the scale
factor for the connection to k . The scale factor affects the
editing done by the F, E, EN, ES, D, and G edit descriptors
for numeric quantities.
So P editing does not even apply to the L descriptor.
