Wanting to scroll messages on a "display"

Maybe this has a chance of working:

// now assuming that message2 is a char array

void another()
{
  for ( int i = 0 ; i < 24 ; i++ )
  {
    for ( int j = 0 ; j < 8 ; j++ )
    {
      int offset = i + j ;
      //Serial.println(offset);
      //
      //Serial.print ( ( offset < 8 || offset > 23 ) ? ' ' : ip[ offset - 8 ] ) ;
      Serial.print ( ( offset < 8 || offset > 23 ) ? ' ' : message2[ offset - 8 ] ) ;
      char ch =   ( offset < 8 || offset > 23 ) ? ' ' : message2[ offset - 8 ]  ;
      byte by ;
      if ( ch >= '0' and ch <= '9' ) by = ch - '0' ;
      else by = 15 ; // space

      //
      MAX7219senddata(j , by );
      //
    }

    Serial.println() ;
    delay(800);
  }
}
