Description
The NEXTKEY() function returns an integer numeric value for the next key pressed at the keyboard, without removing it from the keyboard buffer. The command SET PCKEYS is used to change to return value of the NEXTKEY() function. When SET PCKEYS is OFF, the NEXTKEY() function returns the ASCII code for the key that was pressed. When SET PCKEYS is ON, the NEXTKEY() function returns the IBM PC keyboard value of the key that was pressed. If no key is pressed, the NEXTKEY() function returns 0.
