Attention: Although the default is to prompt the user with messages 711, 716,
717, and 725 when unexpected circumstances arise, these prompts when turned off
will remain off for the rest of that session unless the user turns them back on by
entering PROMPTS ON. DDR users considering the use of PROMPTS OFF should
carefully examine the conditions under which the prompting messages are issued
and then determine whether any adverse effects would result by allowing the DDR
function to continue.
