Answer / nagaraj ramamoorthy
As a good programming practice, it will be good if you
handle/include all possible error combination in the
program. so the file status must be checked in both cases.

Answer / raj
At the time of reading is enough. There is only one case of
getting abend at the time of opening i.e, If that file
doesn't exists.But in general the programmer doesn't open
any file if that one is not exists so there will be no
negative effect if we insert the File status check Opening
file.
