Why not?
data want;
input have :$30.;
want=substr(have,1,findc(have,'.','b')-1);
cards;
12.2.3.4
12.33.44.55
122.333.333.55
;
Or, if the number of "parts" varies:
data want(drop=pos len);
input have :$30.;
call scan(have,3,pos,len);
want=substr(have,1,pos+len-1);
cards;
12.2.3.4.5
12.33.44.55.66.77
122.333.333.55.6.77.888.9
