Keywords

Keywords are special words reserved by the compiler. They cannot be used as parameters or variables, since they have a special meaning in the formula language. Here is a complete list of keywords:

bool
color
complex
else
elseif
endfunc
endheading
endif
endparam
endwhile
false
float
func
heading
if
int
param
repeat
true
until
while

Starting with Ultra Fractal 5, there are also new semi-reserved keywords. These act as keywords in the right context, but they can also still be used as variable names for compatibility with formulas written for earlier versions of Ultra Fractal. This is not recommended, of course. Here is a complete list:

const
import
new
return
static
