Thanks for the replies. I guess I have always created
these kinds of variables in order in the dataset, so references
like com1-com45 always did what I thought they should. Funny
how one can learn wrong.

try d com* or egen total=rtotal(com*)
you might also look at the -aorder- command

And I discovered it when
. egen total=rtotal(com1-com45)
totalled all the -medcom- variables as well. How can I reference
just those variables that start with -com-?
thanks,
