INPUTERR [message [, ...] ]
|message||Optional — A string literal to write to the terminal screen. Can be an expression or variable that resolves to a literal value. If omitted, a blank line is written.|
The INPUTERR statement performs several operations affecting the user terminal.
It advances the terminal cursor to the last line of the current page. For further information on page lines refer to the SYSTEM function and the ASSIGN statement
It writes the optional message to the terminal screen at the new cursor location. If you specify multiple comma-separated message arguments, they are displayed with tab spacing, similar to the PRINT or CRT command. You can also concatenate multiple message arguments, using the colon (:) concatenation operator.
It deletes (clears) any user input data stored in the type-ahead buffer. This affects the INPUTIF statement, which receives user input from the type-ahead buffer.
The message is cleared by the next INPUT @(col,row) statement.
Caché and UniVerse clear user input data stored in the type-ahead buffer. All other emulations do not perform this action.
