Enter data using bar codes or keys.

Pressing a key limits input to keys until the user presses the ENT key.

When any echoed back data is displayed on the BHT screen, pressing the C key erases the whole displayed data; pressing the BS key erases the most recently typed-in character of the data.

Use the WAIT statement to wait for bar code or key input.
Use LOC function to monitor bar code input.
Use INKEY$ function to monitor key input.
Do not use INPUT# statement to monitor key input. This statement suspends the user application program until key input, so can not simultaneously wait for either type of input.
