Answer / sandy
Opening a file will give a file status code of '0' and
not '10'. Only when reading, file status will be '10'

Answer / renu
Open the file and check the file code. If it is '10', the file is empty. It is always better to check the file code after every open statement and handle the empty file condition.

file is empty, you will get condition code 4 otherwise you
will get cc '0'.

Goto ISPF 3.4, give the dataset name hit enter.
Press F11 until you see '%used', if its zero then the file
is empty. This will be useful if you want to validate many
GDG's for emptiness.
