Subject   st: Problem defining syntax for program

Dear list 
I am writing a Stata program and am encountering some problems with defining the syntax. The program is designed to estimate power for comparing ROC curves. When I run the program I obtain the following error (with set trace on). 
  
rocpower , area0(0.5) area1(0.6) n(100) percent(0.25) 
--------------------------------------------------------------------------------- begin rocpower --- 
- syntax, area0(real 0.50) area1(real 0.50) n(integer 100) [area2(real 0.50) na(integer 50) 
nn(integer 50) percent(real 0.50) r(real 0) alpha(real 0.05) tails(integer 2) I(integer 2) J(integer 1) 
ordinal] 

invalid syntax 
  
The program was called using the statement: 
  
rocpower , area0(0.5) area1(0.6) n(100) percent(0.25) 
  
I have looked over the syntax help several times but I can't seem to locate the problem. Any advice or suggestions would be much appreciated.
