Creating SAS dataset using datalines gives error if written inside a macro

The error is something like this:

ERROR: The macro X generated cards (data lines) for the DATA step which could cause incorrect results.

The DATA step and macro will stop executing.

The solution is to insert the values in a table using proc sql.

The sample code below demonstrates the same.

options nomlogic mprint nosymbolgen;

%macro insertData;

proc sql;

create table class

(Semester char(25) ,

Professor char(24),

Location char(12),

Cost num(5));

quit;

proc sql;

insert into class

(Semester,Professor,Location, Cost)

values('Fall','Dr. Armstrong','London',3000)

values('Spring','Dr. Armstrong','Prague', 3300)

values('Spring','Dr. Hannity','Beijing',3000)

values('Fall','Dr. Hannity','London',3000)

values('Spring','Dr. Smith','Prague',3300)

values('Fall','Dr. Smith','Los Angeles',3800)

;

quit;

%mend insertData;

%insertData;
