WRITEIO Statement

 
The WRITEIO statement writes a data value to an interface hardware register. If a valid interface select code and interface register number are specified, then the data value is written to the hardware interface register. For Example:
 
WRITEIO 7,3;Regdata
 
writes the value of the variable Regdata to register number 3 on interface number 7. Again, extensions to READIO and WRITEIO are explained below.
