This is an intermediate though working release. A large COMPASS driven modification work has been started but not fully finished. New features:

• NTUPLE writing. It is working, though the detector data will be modified in near future.
• Pileup with the beam and with halo have been implemented.
• In order to treat the pileup the implementation of time gates for all detectors and for drift detectors in particular has been implemented.

This is deemed to be the first release for COMPASS. The repository module is now called "comgeant" and contains the code, scripts, data and documentation.

New features:

• The Obelix magnet is implemented (MAGNET4) by Massimo Lamanna.

Since the field map for the Obelix magnet takes more than 40Mb and interactive GEANT takes about 30Mb this version does not run on all platforms:

• cernsp (aix) - OK
• dxplus (osf) - OK
• hpplus (hp) - NO It tried to load 108Mb, then tried to dump 108Mb core and then died.
• ULTRIX of WA89 - NO - "not-enough core".

In future one has to reconsider this field map. Meanwhile if one has to run on a "wrong" platform but does not need the Obelix magnet - one can relink the executable with dummies for OMGAINI4, OMAGINI4A and OMAGFLD4.

Still missing, but close to implementation:

• NTUPLE detector information. At the moment the detector/geometry information for the reconstruction should be taken from the generated file detectors.dat.
• NTUPLE reading by COMGEANT. The first application would be to read and use the LUND data.
