ckkeywd - prompts for and validates a keyword


     ckkeywd [-Q] [-W width]  [-d default]  [-h help]  [-e error]
     [-p prompt] [ -k pid [-s signal]] keyword [...]


     ckkeywd prompts  a  user  and  validates  the  response.  It
     defines, among other things, a prompt message whose response
     should be one  of a list of  keywords,  text  for  help  and
     error  messages, and a default value (which will be returned
     if the user responds with a carriage  return).   The  answer
     returned  from  this  command  must match one of the defined
     list of keywords.

     All messages are limited in length to 70 characters and  are
     formatted automatically. Any white space used in the defini-
     tion (including newline) is stripped.  The -W option cancels
     the  automatic  formatting.  When  a  tilde is placed at the
     beginning or end of a message definition, the  default  text
     will  be  inserted  at that point, allowing both custom text
     and the default text to be displayed.

     If the prompt, help or error message  is  not  defined,  the
     default message (as defined under NOTES) will be displayed.


     The following options are supported:

     -d default
           Defines the default value as default.  The default  is
           not  validated  and  so does not have to meet any cri-

     -e error
           Defines the error message as  error.

     -h help
           Defines the help messages as  help.

     -k pid
           Specifies that process  ID pid is to be sent a  signal
           if the user chooses to abort.

     -p prompt
           Defines the prompt message as prompt.

     -Q    Specifies that quit will not be  allowed  as  a  valid

     -s signal
           Specifies that the process  ID pid defined with the -k
           option  is  to  be  sent  signal   signal when quit is
           chosen. If no signal is specified, SIGTERM is used.

     -W width
           Specifies that prompt, help and error messages will be
           formatted to a line length of width.


     The following operand is supported:

           Defines the keyword,  or  list  of  keywords,  against
           which the answer will be verified.


     The following exit values are returned:

     0     Successful execution.

     1     EOF on input, or negative width on -W  option,  or  no
           keywords from which to choose, or usage error.

     3     User termination (quit).
