The error is easy to explain. Imagine you are Stata. Second time round
the loop -fathliv- already exists, so you can't create it afresh.
Otherwise I see no need for and no point in a loop. Just specify the
varlist. Very likely
egen fathliv = anymatch(fammem*), v(2)
catches what you want.
For the record, an equivalent loop is
gen fathliv = 0
qui foreach v of var fammem* {
replace fathliv = 1 if `v' == 2
}
That's actually much less Stata than implied by the -egen- command,
although more to type.

I need to create a binary variable that equals 1 of one of the variables
fammem1, fammem2, fammem3, fammem4, ... fammem10 equals 2, and 0
otherwise.#I came up with the following solution:
egen fathliv = anymatch(fammem1 fammem2 ... fammem10), v(2)
and it seems to work, but I would like to create a loop rather than
listing the ten fammem variables individually.
I tried:
forv i=1/10{
egen fathliv = anymatch(fammem`i'), v(2)
}
But this gives me an error message and I am not sure why.
