3474  * DO_JUMP overwrites the "obj" variable of the loop and sets it to the target

3477  * regularly, "obj" is being updated to point to obj->next, so object parsing
3478  * continues right after the corresponding ELSE or ENDIF. This means that if we
3479  * find an ELSE, it's corresponding IF must not have jumped, so we need to jump
