SAS date formats

I'm new here and while I've read a bunch on this nothing I do helps. I know this is a newbie question but I am thankful for the help!

Basically I want SAS (9.3) to read the date format I have here and output a date. I currently get the "SAS date value".

DATA Chap3.myfirstdata;
INPUT name $ dateofbirth date9. ;
Leo 17FEB1977
Martin 24May1969

So, for instance, my output says "Leo 6257 Martin 3431" and I'd like it to say "Leo any variation of Feb 17,1977"
