NAME

       ckint, errint, helpint, valint - display a prompt; 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 width] [-b base] [-e error]

       /usr/sadm/bin/helpint [-W width] [-b base] [-h help]

       /usr/sadm/bin/valint [-b base] input

DESCRIPTION

       The ckint utility 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 new-
       line)  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.

OPTIONS

       The following options are supported:

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

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

       -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 response.

       -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.

OPERANDS

       The following operand is supported:

       input	Input to be verified against base criterion.

EXIT STATUS

       The following exit values are returned:

       0    Successful execution.

       1    EOF on input, or negative width on -W option, or 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	0 for success and non-zero for failure.
