NAME
ckint - 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]]
errint [-W width] [-b base] [-e error]
helpint [-W width] [-b base] [-h help]
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 is returned if the user responds with a
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
is 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 NOTICES) is 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 includes the expected
base of the input.
The options and arguments for this command are:
-Q Do not allow quit as a valid response.
-W Use width as the line length for prompt, help, and error
messages.

-b The base for input is base. Must be 2 to 36, default is
10.
-d The default value is default. The default is not
validated and so does not have to meet any criteria.
-h The help message is help.
-e The error message is error.
-p The prompt message is prompt.
-k Send process ID pid a signal if the user chooses to
abort.
-s When quit is chosen, send signal to the process whose
pid is specified by the -k option. If no signal is
specified, use SIGTERM.
input Input to be verified against base criterion.
EXIT CODES
0 = Successful execution
1 = EOF on input
1 = Usage error
3 = User termination (quit)
NOTICES
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 does not
produce any output. It returns zero for success and non-zero
