The ckpath utility prompts a user and validates the response. It defines, among other things, a prompt message whose response should be a pathname, text for help and error messages, and a default value (which is returned if
the user responds with a RETURN).
The pathname must obey the criteria specified by the first group of options. If no criteria is defined, the pathname must be for a normal file that does not yet exist. If neither -a (absolute) or -l (relative) is given, then either is assumed to be valid.
All messages are limited in length to 79 characters and are formatted automatically. Tabs and newlines are removed after a single white space character in a message definition, but spaces are not removed. 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 EXAMPLES) is displayed.
Three visual tool modules are linked to the ckpath command. They are errpath (which formats and displays an error message on the standard output), helppath (which formats and displays a help message on the standard output), and valpath (which validates a response). These modules should be used in conjunction with Framed Access Command Environment (FACE) objects. In this instance, the FACE object defines the prompt.
