It is treated as a set of flags - if bit 1 is set then it is added to the players traits, if bit 2 is set it is added to the players perks, and if bit 3 is set it is removed from the list of selectable perks.

 show_iface_tag, hide_iface_tag and is_iface_tag_active relate to the boxes that appear above the interface such as SNEAK and LEVEL. You can use 3 for LEVEL and 4 for ADDICT, or the range from 5 to 9 for custom boxes. Remember to add your messages to intrface.msg and set up the font colours in ddraw.ini if you're going to use custom boxes. Starting from sfall 3.8.12, is_iface_tag_active can also be used to check 0 for SNEAK, 1 for POISONED, and 2 for RADIATED.
