Java API for MOCHASOFT

["Larry" <larryhytail@xxxxxxxxx>]

Mochasoft has a java api for its java based emulator that allows one to screen 
scrape.  I have a few *limited* instances where screen scraping would be an 
enormous benefit.  This program is really inexpensive and the API looked easy 
so I tried it out.

I was quickly able to get the sign on screen and effectively sign on and get to 
the next screen.  No problem.

But what I can't seem to do is to get the buffer for any screen after the 
intial screen.  Repeated calls to do_read_all() even after a do_wait_input(100) 
get the original buffer data for the sign on screen.

I tried longer waits, changing byte variables, NULLing out the buffer array 
before the next calls and get the same results.  Since I can watch the session 
in a separate window I know I am moving to new screens on the 400.  It just 
isn't reflected in the do_read_all().

Has anyone used this API?  I was hoping that perhaps someone may have a simple 
example of a multi-screen screen scrape that works.

A very simple sample of my test program is shown below for those that want to 
look.

Thanks,

Larry

        public static void main(String[] args)

        {
                byte buf[][];  // screen 
                
                byte ttt[]={72,72,71,71,71,71,71,72,72};   // very simple 
password hiding
                String sss = new String(ttt);                        // save 
password as string for later use

                a.use_display(false,true); // hidden,standalone 
                
                if (a.do_connect("mySystem",23) == true) { 
                        a.do_wait_input(0); 
                        buf = a.do_read_all();

                        a.do_goto(18,6);
                        a.do_write_text(sss);  //password
                        a.do_aid_key(0xf1); //enter key
                        
                        a.do_wait_input(0);
                        buf = a.do_read_all(); 
                        
                                //Print out first line of screen for 
identification
                int x=1;
                                for (int y=0;y<buf[x].length;y++){
                                        System.out.println(x+":  "+buf[x][y]+" 
: "+(char)(buf[x][y]));
                                }
                                System.out.println("");
                        
                        a.do_disconnect(); 
                        System.out.println("\nDisconnected");
                }
                System.exit(0);
        }
}
