# To add this script to your installation, change the user defined variables
# below to match your envrironment and taste, then put it in
# $BBHOME/ext (on the machine where BaaN runs-NOT your BBDISPLAY machine-
# unless, of course, they happen to be one and the same in your case...)
# and add it to your $BBHOME/etc/bbdef.sh file. Also, on your BBPAGER
# system remember to update the svcerrlist token in the bbwarnsetup.cfg file.
# Restart the bb client and be happy.
#
# This was tested and functions on a Solaris 2.6 box with bb15d2 client,
# bbdisplay is Mandrake 7.2 with bb16d install. Works for me. YMMV.
#
# USER DEFINED VARIABLES:
#
#
# Set BaaN temp dir here

# Enter space available for red warning

# The ' ' in the "" construct is replaced with '&_' temporarely
# until the string is actually used which is reverted back to ' '
#
# That's because a constrcut like "syslogd -s" in BBPROCS would
# appear as "syslogd and -s" in the for loop if no substitution
# was done:
# for proc in $BBPROCS  -> would become for proc in "syslogd -s"
