Cheryl,

       Yes, what they are describing can be done under ZCPR3 quite
easily.  In a sense, it has already been done.  ZCPR3 has a facility
which I call Error Handlers.  These programs are invoked when an error
in the command line occurs.  The ZCPR3 CP leaves a message to its
Error Handler which points to the command in error.  The Error Handler
can then do whatever it wishes.

       There are currently five different Error Handlers with ZCPR3.
Two of them display the command line which was in error and the rest
of the commands on the multiple command line buffer.  They then give
the user the option of reentering the erroneous command, advancing to
the next command, entering a whole new command string, or flushing the
entire command string.  This does what the UNIX people were talking
about, but, rather than advancing to the next command being automatic,
the user has to manually choose to do so.  It would not hurt to create
another Error Handler which just skips to the next command.  I will
log your message and do so if I have the time.  Thanks for the input.

       Rick
