I prefer the current method as there is no doubt about what the syntax 
means (lower values in top left unless you specify /SD) and the /SD 
switch provides a means of inverting the order. Many people code 
variables as 1=Yes 2=No, which gives a proper RR without the /SD switch. 
Many others use 0=No 1=Yes, which requires /SD. Since EpiData internally 
treats Booleans False as 0 and True as 1, the current approach allows 
programming that does not require exceptions. User help and guides 
should point this out. The TAB output clearly identifies the meaning of 
the RR, which is something a number of us requested. This is something 
that came into later versions of EpiInfo to help the user avoid 
misunderstanding.

So no need for EPITABLE - just use TAB OUTCOME EXPOSURE /RR /SD
