Hello data _null_,

Yes, you are correct on both counts. Sorry for the trouble you had
determining what the output should look like. I am trying to code most
significant source of HIV exposure. The hierarchy from top to bottom is:

MSM/IDU
MSM
IDU
Blood
Endemic
Heterosexual
Other/Unknown

So, for example, if a patient has exposure via:

1) men having sex with men and intravenous drug (MSM/IDU) and
2) Immigration from an HIV endemic region (Endemic),

they will be assigned the code MSM/IDU.

Thanks for your help.

Paul
