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 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.
