Hi Anandkvn,

All you need to do is add / to your list of separators:

data work.ds_scan_slash;
    set work.ds;
    my_scan_slash = scan(my_string, 3,'/*');
run;

Hope this helps.

@LeonidBatkhan's answer is a good one.

You could also translate the '*' to a '/" and then scan. Like this:

data work.ds;
    input my_string $1-50;
    datalines;
World/Europe*Spain/Madrid
World/Europe*France/Paris
World/Latin-America/Argentina/Buenos Aires
World/Latin-America*Peru/Lima
;
run;
 
data work.ds_scan_slash;
	set work.ds;
	     
	My_String		=	TRANSLATE(My_String, '/', '*');
	my_scan_slash 	= 	scan(my_string, 3,'/');
run;
