ENTER KBD reads information from the keyboard.
The INPUT and LINPUT statements also read information from the keyboard but are designed especially for the keyboard and provide some features not supported by ENTER.
The number builder rules are not the same for the two.
ENTER KBD uses rules consistent with ENTER from other sources and is useful for verifying I/O program correctness. Toward this end, an EOI signal can be generated from the keyboard by entering Ctrl-E before the character to be sent with the EOI signal. This pseudo-EOI must be enabled with CONTROL KBD,12;1. No keystrokes are entered into ENTER items until the ENTER key is pressed. If ENTER is pressed, the buffer is transmitted with CR/LF appended to the buffer. If CONTINUE is pressed, the present keyboard buffer is transmitted through the I/O path to the ENTER statement with no appended end-of-line characters.
