INPUT CLEAR Statement
Clears any keystrokes buffered from the keyboard, discarding any type-ahead characters. The INPUT CLEAR statement is useful when you want to make sure Progress clears out extra characters in the input statement that could follow a field entry that is too long.
SYNTAX
EXAMPLE
This menu procedure tests each key the user presses. If the user presses a key other than 1, 2, or 3, Progress clears the keyboard buffer and displays a message.
NOTES
- On Windows, the keyboard type-ahead buffer can contain a maximum of 16 characters.
- If the current input source is not the keyboard, the INPUT CLEAR statement has no effect.
- INPUT CLEAR is not available on the Windows GUI platform after Progress Version 7.3D. It is available for Windows character and non-Windows GUI or character platforms.
