*Switches*
-s - Display variable assignment value.
-g - Creates a global variable instead.
-n - Treat the value as plain text, even if arithmetic operators are used.
*Parameters*
<%var> - The variable to set.
[[= ]value] - Value to set the variable to. (can be a single arithmetic expression, see [[Arithmetic Operators]])

var %result = 1, %x = $1
while (%x) {
var %result = %result * $v1
dec %x
}
return %result
}
