One case that is missing from your example: Sri
Should that become Srx or should it become Srxx?
At any rate, here are the basic tools that you can modify if needed:
if length(var2) > 2 then substr(var2, 3, 2) = 'xx';
You can use substr() function along with IF condition:
data want;
set ds;
if length(var2)<=2 then new_var=var2;
else if length(var2)=3 then new_var=substr(var2,1,2)||"x"||substr(var2,5);
else new_var=substr(var2,1,2)||"xx"||substr(var2,5);
run;
Another alternate solution will be using the Perl expression:
data want;
set ds;
new_var=substr(var2,1,2)||prxchange('s/[a-z][a-z]/xx/i',1,substr(var2,3));
run;
