I am sorry for using a jargon here. And thanks for your answers.
My question is if there is way I can get "_Irs1234567_1Xrs7654321_1" instead
of getting "_Irs1Xrs~1_1" in report. When I run hundreds of such logits, I
need to use Perl (a parsing language) to extract results from Stata log
file. It will be nice if Perl can find real variable names instead of
abbreviation.
Thanks!

The first part is right, but _not_ the second.
Once you have created the dummies, -xi- has no extra role to play.

I think you need to multiply the original variables first and then place an
i. next to that new variable.
gen Irs1234567_1Xrs7654321=rs1234567*rs7654321
xi: logit case sex i.Irs1234567_1Xrs7654321, or
