			This file depends on ItemStatCost.txt.

A stat must be defined there in order to use its ID in the stat1-7 fields.

The bulk of the file consists of seven function blocks. Each block has a function index (FuncX) and three parameters (SetX, ValX, StatX).  Parameters are only useful if the underlying function is written to interpret them.

A '*' in the field name means it is a comment field not loaded into the game.

code: Property identifier to use in other txt files anywhere a property is applied (e.g. MagicPrefix, MagicSuffix, Automagic, MonProp, Gems, Runes, Sets, SetItems, UniqueItems, Cubemain).

*done: 1 if the property is active (boolean).

set1 to set7: Parameter to the property function, if the function can use it (see Color property)

val1 to val7: Parameter to the property function, if the function can use it (see class skills properties).

func1 to func7: Function used to assign a value to a property (see list below)

stat1 to stat7: Stat applied by the property (see ItemStatCost.txt), if the function uses it.

*desc: Description of the property

*param: Description of the param value

*min: Description of the min value

*max: Description of the max value

*notes: Additional comments

*eol: Terminator field, not used in game, primary purpose is to keep Microsoft Excel from misbehaving.

APPENDIX: Functions of Properties.txt

Here are some functions used by the properties.txt to link param/min/max value to the actual bonus of the properties.
