I would like to automate the following commands into a script.  What I cannot 
find in the manuals is how to test
If a command completed with a status of success.  I would like to do this test 
between commands so the next command
only executes if the previous one succeeds.  If a command fails, I would like 
the script to end.  Below are the commands.

backup stgpool MDOR_DISK_STORAGE_POOL OFFSITE_TAPES_DAILY
backup stgpool MDOR_DISK_STORAGE_POOL OFFSITE_TAPES_WEEKLY
delete volhistory type=dbbackup todate=-5
