Stuck with arrays

[emma19901]

Hi, everybody, I have this dataset with 12 variables I am trying to calculate the CCI index for the variables. I am using this code but I am getting twice the variables without changing yes or no to its proper numeric value per condition. The code is the following. Also attached is the original csv file.

data risk;
set datasets.riskdata;
if diagnosis= 'TYPE1_DM' then diagnosis='y';
if diagnosis='TYPE2_DM' THEN DIAGNOSIS='n';
if diagnosis= 'PXECTMY'  then diagnosis='n';
if los<0 then los=.;
array a{10} diagnosis dialysis lipiddis cbv_ds pvd neuropthy respprob cancrpre cbypass mi;
do i=1 to 10;
if A{i}=' ' then a{i}=.;
if a{i}= 999 then a{i}=.;
if a{i}= u then a{i}=.;
if a{i}= 9 then a{i}=.;
drop i;
end;
array b{10} diagnosis dialysis lipiddis cbv_ds pvd neuropthy respprob cancrpre cbypass mi;
array c{10} (2,3,2,1,1,1,1,3,1,2 );
do i=1 to 10;
if (B{i})='y' then CCI = CCI + B(c{i});
if (B{i})= 'n' then B(c{i})=0;
else if (B{i})='.' then CCI+B(c{i})=0;
drop i;
end;
run;

  and this is the error message

1. You cannot change types in place. 

if A{i}=' ' then a{i}=.;

This indicates that a(i) is a list of character variables but then you try and set it to missing for numeric?

 You need a new set of variables for type conversion with new names.

2. This is checking if the variable a(i) is equal to the variable u. I'm assuming you're actually looking for the text u, which means it needs to be in quotes.

if a{i}= u then a{i}=.;

3. You declare the same array twice. B and A are the same and you don't need to reference them twice.

array b{10} diagnosis dialysis lipiddis cbv_ds pvd neuropthy respprob cancrpre cbypass mi;

I've highlighted several of your issues. I suspect #1 is the biggest issue you're dealing with here.

No idea what a CCI index is but I would guess the following code could be close:

data risk;
set datasets.riskdata;
if diagnosis= 'TYPE1_DM' then diagnosis='y';
if diagnosis='TYPE2_DM' THEN DIAGNOSIS='n';
if diagnosis= 'PXECTMY'  then diagnosis='n';
if los<0 then los=.;
array A{10} diagnosis dialysis lipiddis cbv_ds pvd neuropthy respprob cancrpre cbypass mi;
do i=1 to 10;
    A{i} = upcase(A{i});
    if A{i} not in ("Y", "N") then call missing(A{i});
    end;
array c{10} (2,3,2,1,1,1,1,3,1,2);
CCI = 0;
do i = 1 to 10;
    if A{i} = 'Y' then CCI = CCI + c{i};
    end;
drop i;
run;
