This is an example of how to use the SysFileRead function along with the FileReadWriteType structure.

task main()
{
  FileReadWriteType frArgs;
  frArgs.FileHandle = foArgs.FileHandle;
  frArgs.Length = 12; // number of bytes to read
  SysFileRead(frArgs);
  if (frArgs.Result == NO_ERR) {
    TextOut(0, LCD_LINE1, frArgs.Buffer);
    // show how many bytes were actually read
    NumOut(0, LCD_LINE2, frArgs.Length);
  }
}
