Power estimate for CHisquare distriubution

[sasgyro]

I understand the syntax for Proc Power function but I do not know where to get my Primary noncentrality value PRIMNC= for my 2x2 chisquare data. How do I get primary non centrality value?

See the PROC POWER step in Example 3 in the Results tab of this sample program and the related notes in the See Also section there.
