In particular, the following should not pass: ``` //#if MC>=12000 //$$ print(used1) //#else#if MC>=11600 //$$ print(used2) //#else //$$ print(used3) //#endif ``` Because 1. That's supposed to be an `elseif` but it was typo'd (current processor reads it as an `else` without complaints) 2. That's two `else` which probably shouldn't be legal
