I looked it up and here is the beginning of the information:

file    ode/sdassl.f
by      Petzold
for     differential-algebraic system solver
alg     backward differentiation formulae
prec    double
rel     good
age     stable  
gams    I1a2

file    slatec/chk/dedit2.f
for     Subsidiary to DDASQC.
by      PETZOLD, LINDA R., (LLNL)

file    slatec/chk/edit2.f
for     Subsidiary to SDASQC.
by      PETZOLD, LINDA R., (LLNL)

etc.

Apparently the whole package is in Linda Petzold's name and it uses
backwards differentiation formulae.

Best way is to first ask for the index of netlib (if you cannot access
it through mosaic/omni-net):

in the message put only "send index" when sending mail to netlib at ornl.gov
