is it possible to read data from right to left?

[Ksharp]

Why not  parse the whole row to get this age?If height weight were 3 width, id were 3 width, sex were 1 width ,always.

filename FT15F001 temp;
data _null_;
   infile FT15F001 truncover;
   input row $100.;
age=input(substr(row,5,length(row)-10),best8.);
put age=;
   parmcards;
001F36175180
002F9120100
003F110180160
;;;;
   run;
