How to call global macro variable - sas

Question

I have created two global macro variables.
date=10/6/2016
b=simple
I want to create a dataset with variable which refers above macros
below are the variables which i want based on condition.
varible1: Date- which the refers the date macro variable
variable2:condition- if b =simple then condition =y or if b is not equal to simple then condition =n
So dateset will look like below
Date condition
10/6/2016 y

Answer 1

You have two options.
Number one (using macro-variables in a data step):
data result;
format date ddmmyy10.;
date = input("&date", ddmmyy10.);
if "&b" = "simple" then condition = "y";
else condition = "n";
run;
Number two (create macro and generate SAS code based on a macro-variable value):
%macro test;
data result;
format date ddmmyy10.;
date = input("&date", ddmmyy10.);
%if &b = simple %then %do;
condition = "y";
%end;
%else %do;
condition = "n";
%end;
run;
%mend test;
%test
Edited:
Or using PROC SQL:
%let date=12/10/2016;
%let b=simple;
proc sql;
create table result
(
date num format=ddmmyy10.,
condition char(1)
);
quit;
%macro insert;
proc sql;
%if &b = simple %then %do;
%let condition = y;
%end;
%else %do;
%let condition = n;
%end;
insert into result (date, condition) values (%sysfunc(inputn(&date, ddmmyy10.)), "&condition");
quit;
%mend insert;
%insert
