Hi Daniel,
Thank you very much for your help. Sorry for not having found the corresponding text via the -help- function before. I actually needed both, counting the number of variables with value "2":
egen var1 = anycount(var_101-var_110), values(2)
and computing the sum across these variables (sorry for the imprecise question).
Thanks & greetings,
Philipp

Phillip "would like to count for each observation the number of
variables that meet a certain condition, say var*==2."
The very first function in -help egen- is -anycount()- and is described as:
"It returns the number of variables in varlist for which values are
equal to any integer value in a supplied numlist. [...] Also see
anyvalue(varname) and anymatch(varlist)."
However, I am not sure I am getting the problem, because
"[...] computing the sum across variables (for each observation) ONLY
for those variables with values greater than 1"
to me means something comletely different and is not at all
"[...] alternatively, [...]"
to
"the number of variables with values greater than 1 per observation"
Best
Daniel
