If you don't like the - then you may want to read the values as character first then search for  for any other character than / in the character value. If you data is consistetn then 

flag =  (index(characterdate,'/')=0 );

would set a flag of 1 for no / in the value.

then likely follow with

If flag=0 then datevalue = input(characterdate,mmddyy10.);
