Ifvar conditions

ifvar<conditional> <gamevar> <constant>
ifvarvar<conditional> <gamevar> <gamevar>

Ifvar conditions are special if conditions that apply to gamevars. These statements work by comparing the two inputs using the conditional provided as part of the command. If the resulting comparison or operation is true, the game will then execute the code specified. If only one CON command is to be performed, simply put it after the condition. For best reading, put it on the same line or on the following line, indented. For longer chains, enclose the code in curly braces ("{" and "}"). For performance reasons, do not use curly braces for single commands. Else statements can also be used. If you want to do nothing, followed by an else, in place of a command you can write nullop or { }.

Conditional	C/C++	Math	Description
e	==	=	equal to
l	<	<	less than
g	>	>	greater than
n	!=	≠	not equal to
and	&		bitwise AND
or	|		bitwise OR
xor	^		bitwise XOR
either	||		logical OR: either are non-zero

Since CON variables are integer-only, "less-than or equal to" (le, <=, ≤) and "greater-than or equal to" (ge, >=, ≥) conditionals are unnecessary.

Commands with an additional "var" suffix take gamevars rather than constants or defined labels for their inputs. As an alternate short form, "varvar" can be dropped from these commands; for example ife serves an an alias for ifvarvare.
