Hi Catherine,

do you mean the shell variable that is the status of the last executed
command? ( $? in bash shell)

This seems like a quick explanation:

http://www.thegeekstuff.com/2010/03/bash-shell-exit-status/

Sounds like you need to save the standard out and error to a log so
you can evaluate the specific Saxon error:

host# /usr/java5/bin/java ... &>out.log

I can't find the errors that Saxon (through the java runtime) will
return (maybe anything but 0), but the full error code, in the
standard error output, is explained here:

http://www.saxonica.com/html/documentation/javadoc/net/sf/saxon/trans/SaxonErrorCode.html

You could have out.log mailed to you or grepped for the status.
Otherwise, it would take a java class to configure Saxon and evaluate,
as Michael suggests.
