SAS coding help displaying all created variables - sas

Question

I am trying to distinguish recorded subjects who have confirmed hypertension, unaware of their status, and do not have hypertension. My current code only displays bpstatus 1&2 but i missing bpstatus 3 to show up. HTN= (1=hypertension) (0=no hypertension)... HAE(1=Aware of Hypertension) (2=unaware of Hypertension)
data new
set mergedata;
HTN=.;
If SBP >= 140 or DBP >= 90 then HTN = 1;
else if 0 < SBP < 140 and 0 < DBP < 90 then HTN = 0;
run;
proc print data=new;
run;
data new2;
set new;
BPSTATUS=.;
*3-level variable BPSTASTUS;
*diagnosed first;
if HTN=1 or HAE2=1 then BPSTATUS=1;
*undiagnosed;
if HTN=1 and HAE2=2 then BPSTATUS=2;
*normal;
if HTN=2 and HAE2=2 then BPSTATUS=3;
run;
proc print data=new2;
run;
proc freq data=new2;
table bpstatus;
run;
---------
BPSTATUS
Freq % Cum Freq Cum %
1 2354 67.76 2354 67.76
2 1120 32.24 3474 100.00
Frequency Missing = 4424

Answer 1

In this code:
data new
set mergedata;
HTN=.;
If SBP >= 140 or DBP >= 90 then HTN = 1;
else if 0 < SBP < 140 and 0 < DBP < 90 then HTN = 0;
run;
You initialize HTN to be missing, then set it to either 1 or 0 based on some conditions. In subsequent code, you check for this:
if HTN=2 and HAE2=2 then BPSTATUS=3;
Based on the logic in your first program, HTN will never be 2, which means BPSTATUS will never be 3.
