Hello,

Using National Hospital Dicharge Survey, I want to determine the count of
infections, for example, as first diagnosis, as well as any diagnosis (among
a total of 7).

I have tried:

*Create infectious and parasitic diseases group;
d1inf=0;
if '001' le substr(diag1,1,3) lt '140' then d1inf=1;

anyinf=0;
array d(7) diag1-diag7;
do i=1 to 7;
if '001' le substr(d(i),1,3) lt '140' then d1inf+1;
end;

but I got something like:



      d1inf    Frequency     Percent     Cumulative   Cumulative
                                          Frequency    Percent

What do you think I'm doing wrong? Thank you,
