I had WA4 because of this: AnD <=> and, NOt <=> not, etc.
I had WA9 because of this: empty strings (only spaces) - this is not a command))
I had TLE 13 because of this: we should ignore as a command lines has only a label)
Cool problem))
Good Luck)

Well, now you don't have AC :)

I can also add that you should do some pre calculations to get access to the variables' values and labels' positions with constant time. Logarithmic complexity isn't enough to pass TL.

>Well, now you don't have AC :)

Test 14 was added by me recently, which is why~
The only hint i can give for it is that the code prevented TL #13, but did it in not exactly a proper way.

Took some time to rewrite that crap and retake AC :)

Still don't know what was wrong in TL 14 of the previous solution though.
