I would like to check if a variable value is in a string. if so, return the position or a boolean value. For example, the variable Student takes 1 of the following values: Mary, Mike, Luke. If the value of this variable is in the list &pass_students then the variable Rank takes the value of the position of that student in the string.
%let pass_student = Mary Daniel Luke Adam Eva;
data WORK.CLASS(label='Student Data');
infile datalines dsd truncover;
input student:$8.;
datalines;
Mary
Peter
Luke
Carol
Henry
;;;;
run;
So far, I tried:
data class; set class;
temp="&pass_student.";
rank= find(student,temp,'t');
run;
Which kinda work, but it is case sensitive. How do I fix this? is there a better way to get what I want?
Then your initial code never worked.
I've now changed the this in below code using variable student as 2nd parameter to the function.
data class;
student='Daniel'; output;
student='Alfred'; output;
student='Luke'; output;
stop;
run;
%let pass_student = Mary Daniel Luke Adam Eva;
data class;
set class;
rank= find("&pass_student.",student,'it');
run;
The 'i' switch allows for case insensitive searches. Also as you're searching for words I'd be using findw() instead of find().
%let pass_student = Mary Daniel Luke Adam Eva;
data class;
set class;
rank= findw(student,"&pass_student.",'it');
run;
Hi, this does not work. rank returns 0 for all obs
