Hersh,

The error you are seeing

SAC> rbbf wndbbf_all
ERROR 1203: Could not find VARS section


is because the blackboard files you are trying to read into SAC are
in a different byte order than
the machine you are on. The files can be swapped with a little
effort, but being able to read
blackboard variable files of either byte order should be available in
the next release of SAC.

Cheers,
Brian

Hi SAC help,

I am having trouble reading in files of blackboard variables in the
latest version of sac (101.1) that I created in a pervious version
of sac (100.00). I am running both of these versions of SAC on an
intel mac.

Here is what I get reading the same file (wndbbf_all) into the two
versions of SAC

**** first the old version that works:
/Users/hersh/Desktop/phsii_picked_eves/Event_2007_196_13_08_00 >> /
Applications/sac_old/bin/sac
SEISMIC ANALYSIS CODE [03/01/2005 (Version 100.00)]

SAC> rbbf wndbbf_all
SAC> getbb
SACERROR = FALSE
NUMERROR = 0
SACNFILES = 0
NFILE = D.149.BK.YBH.Z
FFILE = D.014.CI.LRL.Z
.... (it goes on)

**** now the same file in the new version:
/Users/hersh/Desktop/phsii_picked_eves/Event_2007_196_13_08_00 >> sac
SEISMIC ANALYSIS CODE [02/05/2008 (Version 101.1)]

SAC> rbbf wndbbf_all
ERROR 1203: Could not find VARS section

Just looking directly at this file using more in unix, I see that
the first line looks to start with "VARS"
VARS^@^@^@^A^@D^@<BF>blackboard ^@<C2>^@^ASACERRORFALSE
^@<C2>^@^@NUMERROR0 ^@<C4>^@^@SACNFILES 0 ^@<C2>^@^CNFILE D.
149.BK.YBH.Z ^@<C2>^@^CFFILE
D.014.CI.LRL.Z .... (it goes on)

Has anyone found a way to get these blackboard variable files to
work with the new version of sac?

I may have also ran into some trouble with the version of sacio.a
included in this version having some trouble reading header
variables. I am getting this error in a fortran program that I
compiled with this library:
ERROR: Illegal header field name. AZ
ERROR: Illegal header field name. BAZ


Thanks for any help!
Hersh
