SimpleAdd

This post was updated on .
I use my VM translator to translate the SimpleAdd.vm, I got my SimpleAdd.asm



SimpleAdd.asm can run on the CPU Emulator if I add

It can set RAM[0] 256

but, I got a error "in line 1 unknown instruction -@7"
when I test SimpleAdd.asm by SimpleAdd.tst

The "SimpleAdd.asm: in line 1: unknown instruction - @7" message is a VMEmultator error because the VMEmulator is trying to interpret @7 as a VM command.

You need to run SimpleAdd.tst using the CPUEmulator.

[c:/TECS/projects/07/StackArithmetic/SimpleAdd]
% VMEmulator SimpleAdd.tst
SimpleAdd.asm: in line 1: unknown instruction - @7

[c:/TECS/projects/07/StackArithmetic/SimpleAdd]
% CPUEmulator SimpleAdd.tst
Comparison failure at line 2

% diff -c SimpleAdd.cmp SimpleAdd.out

Your ASM code is correctly computing 7+8, but leaving the SP with the wrong value.

Please edit your post to remove the majority of your ASM code so as not to provide a spoiler.
