Problem

Symptoms: Display problem with keyboard merge. When a long prompt is used with the {INPUT} code, the display, when going through the merge with reveal codes on, is greatly distorted. It appears as if the prompt is duplicated continually and the text input is intermixed with the duplicate copies of the prompt. When the input is complete and F9 is pressed, the screen is corrected. This problem does not occur unless Reveal Codes is used. Solutions: The {INPUT} command operates under the same principals as the {STATUS PROMPT}. Neither of these commands are designed to be longer than one line. The two commands are specifically designed to work on the status line only. The status line is the last line of the screen. The status prompt must be rewritten or it will get erased. This is the whole purpose of the command. Only the last line can be rewritten safely. You cannot use multi-line prompts and return control to the document and expect them to be preserved. This command cannot be altered to work in a multiple line environment. The {STATUS PROMPT} was never designed to do this. It is difficult because the document has priority writing to ANY part of the screen, except the status line, and the macro would have to tell WP which part of the screen it has written to so WP will not interfere with it. This is difficult because the {STATUS PROMPT} DOES NOT have that kind of information, so it would have to be a NEW command. The way WP displayed would have to significantly change to resolve these problems.
