portb

Provide port access per byte

Declaration

Source position: portsh.inc line 65

var
  portb : tport;

Default instance of type TPort . Do not free. This variable is initialized in the unit initialization code, and freed at finalization.

Since there is a default property for a variable of this type, a sentence as

portb[221]:=12;

Will result in the byte 12 being written to port 221, if port is defined as a variable of type tport
