Would the foreach command be helpful here?

Subject: st: Follow Up on LTABLE
I am estimating the lifetables for a certain group, e.g. people
diagnosed with cancer type i living in county c in year t ;
This can be done by:
ltable time_in_months, by (i c t)
However Stata tells me:
"by(): too many variables specified"
It only works out when I include just one variable in the brackets of
the by command.
Does anyone know a solution for this problem?
Thanks a lot!!
Johannes
Thanks Paul.
I will calculate the life tables for a certain group with ltable;
However, how can I tell Stata to calculate life tables for a certain
group? In my example it would be the survival function for people
diagnosed with cancer type i living in county c. Is there any by command
or similar in Stata?
Thanks a lot!
Best,
Johannes
