st: ICE in STATA 10.0

[Naomi Spence <njs3536@fsu.edu>]

Has anyone run into trouble using ICE in Stata 10?  When attempting to 
use the passive and substitute options, I get an error message that 
states "Unknown function index()".  I have followed examples and done a 
lot of troubleshooting, but this error message is persistent and I don't 
know the reason for it.  Below is an example of my syntax:

ice depvar age inc emp home south mstat nvrmar widow divsep using imp, 
dryrun ///
       cmd(mstat:mlogit) passive(nvrmar:mstat==1 \widow:mstat==2 
\divsep:mstat==3) ///
       substitute(mstat:nvrmar widow divsep)

WHERE mstat is a categorical variable for marital status and nvrmar, 
widow, and divsep are dummy variables based on mstat with married as the 
omitted category.

Any advice/guidance is appreciated.

Thanks,
Naomi Spence
