Hello,

Is there anyway in Fortran that I can do the equivalence of the following C
code?

struct {
  int key;
  union {
    float t;
    int value;
  }
} s;



Not in standard Fortran. There's the old DEC extension UNION/MAP which can
do this. In standard Fortran one would typically use TRANSFER to deal with
such things.
