NAME
       ckkeywd - prompt for and validate a keyword

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

DESCRIPTION
       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 definition (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.

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

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

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

       -h     Defines the help messages as help.

       -e     Defines the error message as error.

       -p     Defines the prompt message as prompt.

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

       -s     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.

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

       1 = EOF on input
