... or a single string.

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. Nick n.j.cox@durham.ac.uk Elizabeth Allred I just updated my ado files and am now having a problem with the -egen- function, -count-. Fortunately, -rownonmiss- works.
