INP Function
 ----------------------------------------------------------------------------


 Action

 Returns the byte read from a hardware I-O port.


 Syntax

  INP( port)


 Remarks

 The  INP function complements the  OUT statement, which sends a byte to a
 hardware I-O port.

 The argument  port identifies the hardware I-O port from which to read the
 byte. It must be a numeric expression with an integer value between 0 and
 65,535, inclusive.

 The  INP function and the  OUT statement give a BASIC program direct control
 over the system hardware through the I-O ports.  INP and  OUT must be used
 carefully because they  directly manipulate the system hardware.


 Note

 The  INP function is not available in OS-2 protected mode.
