Several days ago I asked about how to combine veteran status in the 2007-2014 NHIS by combining armfev (2011-2014) and hondscg (2007-2010). Erin Meyer wrote back: " 0It is possible to merge these variables in the statistical package of your choice. One way this can be accomplished is to create a new variable such as VETSTAT. Then you can write syntax indicating that in years 2007-2010 HONDSCG=VETSTAT, and in years 2011-2014 ARMFEV=VETSTAT. This will combine the two variables into one veteran status variable."
But how would you do this in the on-line analysis system? As far as I can tell, the recode option cannot handle this.
