Thanks for the additional syntax hints.  On solaris I ended up having to 
use
 smcstop = ( ReturnsZero(/usr/xpg4/bin/sh -c "/usr/bin/netstat -an | 
/usr/xpg4/bin/grep -q 898")

before it would work...

Somewhat offtopic, but would anyone mind giving a brief synopsis of what 
the /usr/xpg4 stuff is?

I didn't realize I was going to have to initiate it's own shell to 
accomplish it, but I got a bunch of errors without initiating 
/usr/xpg4/bin/sh.

I tried ( ReturnsZero(/usr/bin/netstat -an | /usr/xpg4/bin/grep -q 898) )
and got invalid argument arguments for netstat

I tried it with single quotes and double 
( ReturnsZero('/usr/bin/netstat -an | /usr/xpg4/bin/grep -q 898')  )
( ReturnsZero("/usr/bin/netstat -an | /usr/xpg4/bin/grep -q 898")  )

cf:cfengine::/var/cfengine/os/solaris/cf.solaris:18: ExecResult(/command) 
must specify an absolute path


The good news is it works now.  Thanks for the help.
