macro for 'combinations'

K_S — Sat, 25 Mar 2017 00:27:23 GMT

pt ID	sex	service ID
12	M	22
22	F	34
22	F	77
24	M	47
24	M	24
845	F	23
2384	F	99
4905	M	96
95	M	52

Could somebody help me create a macro that prints pt ID for any combination of sex and service ID? Service ID s go from 1 to 99.

I have an idea of how to do this but I wanna see if there is a better, more logical way.

Thank you in advance!

Not sure what you want. Do you want 99 records for every pt_id?

hmmm....nope. I have thousands of patients and 99 codes and 2 sexes.
so for every combination of sex and code, I want to print the pt IDs
for example I want to know the IDs of all the patients who are M and are in
for a 64 ( which is psychiatric services), and so on and so forth. A macro
could do this..

If I correctly understand, you may only need something like:

proc sort data=have;
  by service_id sex ;
run;

proc print data=have;
  var pt_id;
  by service_id sex ;
run;

hmm...no, not what I am looking for. It has to be a macro that would allow
me to randomly pick combinations of sex and service IDs.
Let's say today I want to get the IDs of all the males who are in for a 64,
but then tomorrow I want to look at women who are in for a 52.
I am sorry if I am not making a lot of sense. I am new to this and not
entirely sure what I am being asked to do. All I know is that it has to be
a macro that would allow me to get pt_IDs for any combinations of sex and
service id.

You don't need a macro, but here is one way to do it without a macro and one way using a macro:

proc print data=have (where=(sex eq 'M' and service_id eq 22));
  var pt_id;
  by service_id sex ;
run;

/*or*/

%macro doit(sex,service_id);
  title "Patients with Gender = &sex. and Service_ID = &Service_ID";
  proc print data=have (where=(sex eq "&sex" and service_id eq &service_id));
    var pt_id;
  run;
%mend doit;

%doit(M,22)
