FORTRAN array read behavior

Question

Suppose G is a (large) two-dimensional array. If I save the array by writing G to a text file as in:

  WRITE(1,*) G

and then later in a separate subroutine I try to recover by doing this:

  READ (1,*)  G

Will the READ statement keep reading all the lines of the text file until G is filled up with values? Basically, how "smart" is this read statement in this context?

Answer 1

Yes. A list directed read statement will continue reading records until it has satisfied the list of input items or run out of file.
