Actually, I'm constructing an interface for an old fortran program.
For this task, I'm using the wxWidgets GUI library, and calling fortran subroutines when necessary.
At the beginning, I was developing the…

...
RETURN
END
Which is called in another subroutine by:
CALL SSUB(W(0,1,0,1),...)
where W is a 'working array'. It appears that a specific…

Just a simple call that would return me a double precision result.
The problem is whether I should declare the function at the start of my script. I found that if I don't declare it, and when I compile the code in…
