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
