Hello!

I think you want to do this :--

gen j=var1

gen j2=subinstr(j,"Mrs","",1)
gen  j3=subinstr(j2,"Mr","",1)
gen j4=susinstr(j3,"Ms","",1)

Note  the order of j2 and j3 , it is needed because we have Mr as as
subsitring of Mrs. It would be ruined if you did it the other way.

I hope you liked it.

Thank you,
Ashim.
