Help on CDF function

[SteveDenham]

I am working on some mixture problems, and thought I would use the CDF function, with the normalmix distribution.  Log info follows: 

31 data two;

32 val=cdf('normalmix',2,.5,.5,0,1,1,1);

33 run;

NOTE: Argument 3 to function CDF at line 32 column 5 is invalid.

val=. _ERROR_=1 _N_=1

Now per the documentation as I understand it, with a second argument of 2, indicating a mixture of two normals, I should give two proportions (pi's in the notation used in the documentation) that sum to 1.  Does anybody have some info as to what I need to change the .5's to in order for this to work?

Thanks,

I left out the value for n--the integer number of mixtures.  Most likely because it is also a two...
