Hello, i've been playing around with some code (as shown below) and for some reason everytime i run this code I am told:

At line 11 of file tester.f90
Fortran runtime error: End of file

I'm not really sure whats causing it, is it the position of my Open file?
Any help would be much aprrieiated :)

PROGRAM tester

!Turn off implicit typing
IMPLICIT NONE

INTEGER :: a, b

OPEN(10,FILE='tester.out')

WRITE(10,*) 'Please give value for a'
READ(10,*) a

IF (a < 0) THEN
WRITE(10,*) 'Wrong number'
STOP
END IF

WRITE(10,*) 'Please give value for b'
READ(10,*) b

IF (b > 0) THEN
WRITE(10,*) 'Wrong number'
STOP
END IF

WRITE(10,*) a * b

CLOSE(10)

END PROGRAM tester

Are you sure the file exists?

You are writing to the file and reading from it simultaneously. This can cause problems if not done carefully.

When opening the file, FORM ='FORMATTED' should probably be used.
