"if" expressions

[glyph]

hi, is there any documentation on slightly more complex 'if' expressions?

for instance I have this:

if($PT%2==0,$TY+((sin($F*4)+1.8)*0.15),$TY)

so what I'd like to know is, is there any way I can redo the query part

like:

if($PT%2==0 AND $PT<80 etc..

or replace AND with OR

...again in other software I was able to do nested if statements -- (also a nice variant of that called 'case' statements which was just a neat way of listing choices out without nesting..)

thanks

Hi there,

the operators are the standard programming operators:

OR = ||

AND = &&

if( $TX==0 || $TY==0, 1, 0 )

As for nesting, you can put if() statements inside of other if() statements:

if( A==B, if( C==D,0,1), 0)

Hope this helps,

Jason

thanks again Jason - just what I needed to know rather than going at it randomly!
