Ciao a tutti,
Starting with RUN 18631 of 23-NOV-1999 I have changed the FFREAD and
executable for the so called GC DSTs. Effective this RUN/day:
1) data are written out in RAW format, not ZEBRA. This implies that all
   TAPE archiving will be performed from now on with the NOT FOREIGN option
   GC DSTs produced so far were written in FZEX and two versions of tape
   archiving were produced (FOREIGN/not FOREIGN). This was true until GCD11
   but it will no longer be supported. The RAW output saves a ~10% overhead
   that comes from ZEBRA. Files now have the extension *.DAT rather than
   *.ZDST
2) No selection is imposed on ID's. Previously I had selected only
   ID=1/10/20. This was resulting in losing the END OF RUN ERP GC readout
   which was read by the data acq as ID=6 but swapped within DREAM to ID=1
   after the IDSL. With the new GC DST, all ID/eqp are kept with the
   exception of PHRASE TRIGGERs and EQP 42/6042
3) Bugs in DSHRNK, DEQSH and DFRAW were fixed. This was responsible for
   ZEBRA fatal errors.
A presto,
--Erik
