This isn't an -update- problem. 

The argument saa1 saa2 saa3 is not an expression, so your syntax is
illegal now and was illegal before the -update-. 

An expression is here whatever evaluates to a single number for each
observation.

I just updated my ado files and am now having a problem with the -egen-
function, -count-. Fortunately, -rownonmiss- works.

Stata 11.1 completely up-to-date on Windows.

. egen count1=count(saa1 saa2 saa3)
saa1saa2saa3 not found
r(111);

. egen count2=rownonmiss(saa1 saa2 saa3)

. tab count2

     count2 |      Freq.     Percent        Cum.
