Thank you very much, Baum and Nick.
I understood the use of -subinstr-, -word- and -strpos- with your help.
Another problem is how to deal with it if the strings excluded from
another string variable is not consecutive.
for example,
clear
input str10 (v1 v2)
ab123d 12d
efg34 f4
end
I want to get v3 as followings
v3
ab3
eg3
