st: Re: error message- invalid syntax

["Michael Blasnik" <michael.blasnik@verizon.net>]

see -help return-.  It tells you that you need to tell Stata what kind of 
result to return.  You probably want -return scalar bssamir =...

You can suppress the output of summarize using quietly  (quietly summarize 
....), or in the example you give, you can just use the meanonly option 
which automatically supresses the output (summairze ..., meanonly) and also 
works a little faster.
