As I understood the description, the choice of what to do with the next
command depended on the previous command being CORRECT, executed, and
the PROGRAM returning a completion code. This is quite different from
deciding what to do if the COMMAND LINE itself is in error. In most
cases you would want to abort, fix up the command line and restart.
