Error when attempting to run VMEmulator (Project 11)

[SchwerToMe]

Whenever I try to run the VMEmulator on my Main.vm for the folder Seven, I get this error:

Exception in thread "Thread-8" java.lang.ArrayIndexOutOfBoundsException: 101
        at Hack.VMEmulator.CPU.popToSegment(Unknown Source)
        at Hack.VMEmulator.CPU.pop(Unknown Source)
        at Hack.VMEmulator.CPU.executeInstruction(Unknown Source)

        at Hack.Controller.HackController$FastForwardTask.run(Unknown Source)
        at java.lang.Thread.run(Thread.java:745)

I inserted all of the .vm files from the OS folder in tools but cannot get passed this error to test my code.

My guess is that your compiler has written a defective "pop" instruction that for some reason isn't being caught during load.

Please post the Main.vm your compiler generated so I can take a look at it.

function Main.main 0
pop constant 1
pop constant 2
pop constant 3
call Math.multiply 2
add
call Output.printInt 1
push temp 0
pop constant 0
return

You have the sense of "push" and "pop" backwards. You push arguments onto the stack and pop return values.

Ahh, that makes a lot of sense haha. I went back and switched up my writePop and writePush, so I believe it will work now. Thank you!
