Problem description: I do not get a screen output when I run the virtual machine emulator (VME) for the compiled square program.
What I have done:
I compiled the square.jack programs (Main.jack, Square.jack, and SquareGame.jack) using the JackCompiler and got the three ".vm" files. I loaded the eight OS files into the same directory and ran the VME program. I loaded the square directory into the VME program and started the program.
The program square seems to run, but no screen display.
When I type on my computer keyboard, I can see the keys in the space to the right of the VME keyboard. However, the screen area above does not show anything. I have the view set to "screen" and the screen is filled with white space.
I suspect it is some kind of initialization problem.
I wrote and ran the programs up through chapter six a couple of years ago. It worked fine then (after I modified the "bat" files by putting in quotes). I was using a different computer then. Now, I am using tecs-software-suite-2.5 software. I tried running the same program using the old software, but it did not work either.
