I typed your code in and it works for me. I don't get any FILE ALREADY EXISTS error.

I added some lines to read the values in the file.

Here is the code:

Code:

write(*,104) 'R','run.number'
104 format(a1,'-',a10)
print *,'I m entering'
open(unit=1,file='run.number',status='old')
rewind(1)
read(1,*) i, j
read(1,*) k
print *, i, j
print *, k
end

it says
i must appear in a type declaration because IMPLICIT NONE has been used
j must appear in a type declaration because IMPLICIT NONE has been used
k must appear in a type declaration because IMPLICIT NONE has been used

I dont have IMPLICIT NONE in my code.

However, you may have this setup in properties. I assume you are using Plato. Make sure that "Declare Variables" and "Set Gobal IMPLICIT NONE" are not ticked in properties.
