+## Let there be 2 pieces of code - each one storing a different value in memory
+## and halting afterwards. Jump instruction should cause the second piece of
+## code to execute instead of the first. We'll verify that by checking, which
+## value got written.
+
+## Ufortunately, our assembly currently doesn't compute label addresses for us.
+
+# Each of those 4 instructions should get encoded into 1 16-bit word, so they
+# will take 8 bytes total. Hence jump to address 8 is needed to skip them.
