Gets a single input character.
Syntax
IMiameLib.tin()
Return Value
An integer value representing the ASCII code of any key which has been pressed. If no unprocessed keyboard input is pending, then this method call will block until input is available.
Remarks
The tin method may be used to process keyboard input into the main A-Shell window on a character-by-character basis. Because of its blocking nature, the tcki method may be used to determine in advance if input is available.
