ckint(1)                       DG/UX R4.11MU05                      ckint(1)


NAME
       ckint, errint, helpint, valint - prompt for, verify, and return an
       integer value

SYNOPSIS
       ckint [-Q] [-W width] [-b base] [-d default] [-h help] [-e error] [-p
       prompt] [-k pid [-s signal]]

       /usr/sadm/bin/errint [-W] [-b base] [-e error]
       /usr/sadm/bin/helpint [-W] [-b base] [-h help]
       /usr/sadm/bin/valint [-b base] input

DESCRIPTION
       ckint prompts a user, then validates the response.  It defines, among
       other things, a prompt message whose response should be an integer,
       text for help and error messages, and a default value (which will be
       returned if the user responds with a carriage return).

       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.

       Three visual tool modules are linked to the ckint command.  They are
       errint (which formats and displays an error message), helpint (which
       formats and displays a help message), and valint (which validates a
       response).  These modules should be used in conjunction with FML
       objects.  In this instance, the FML object defines the prompt.  When
       base is defined in the errint and helpint modules, the messages will
       include the expected base of the input.

       The options and arguments for this command are:

       -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.

       -b     Defines the base for input.  Must be 2 to 36, default is 10.

       -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.

       input  Input to be verified against base criterion.

EXIT CODES
       0 = Successful execution
       1 = EOF on input
       2 = Usage error
       3 = User termination (quit)

NOTES
       The default base 10 prompt for ckint is:

         Enter an integer [?,q]:

       The default base 10 error message is:

         ERROR - Please enter an integer.

       The default base 10 help message is:

         Please enter an integer.

       The messages are changed from "integer" to "base base integer" if the
       base is set to a number other than 10.

       When the quit option is chosen (and allowed), q is returned along
       with the return code 3.  The valint module will not produce any
       output.  It returns zero for success and non-zero for failure.
