System Calls in stored procedures SE 7.2

I'm running SE 7.2 on AIX 4.3 I can created a stored procedure that makes a system call but cannot give an argument to the system call. I have tried using the example in the manual but it gives an error. Has any one been successful in doing something like this in a sp. system "echo" "blah" Kate Sent via Deja.com http://www.deja.com/ Before you buy.
