Note that hello.foo(a) returns the value of Fortran `a` value. This explains
the printed 2 value.
So, use
>>> a = hello.foo(a)
and not
>>> hello.foo(a)
As Sameer noted in previous mail, passing Python scalar values to Fortran by
reference is not
possible because Python scalars are immutable. He
bizarre
I get
=
>>> hello.foo(a)
Hello from Fortran!
a= 1
2
>>> a
1
>>> hello.foo(a)
Hello from Fortran!
a= 1
2
>>> print a
1
>>>
=
i.e. The value of 2 gets printed! This is numpy 1.3.0

I have
subroutine foo (a)
integer a
print*, "Hello from Fortran!"
print*, "a=",a
a=2
end
and from python I want to do
>>> a=1
>>> foo(a)
and I want a's value to now be 2.
How do I do this?
