     Rand(FLAG)

Rand: `REAL(KIND=1)' function.

FLAG: `INTEGER'; OPTIONAL; scalar; INTENT(IN).

Intrinsic groups: `unix'.

Description:

   Returns a uniform quasi-random number between 0 and 1.  If FLAG is
0, the next number in sequence is returned; if FLAG is 1, the generator
is restarted by calling `srand(0)'; if FLAG has any other value, it is
used as a new seed with `srand'.

   Note: SRand Intrinsic.

   _Note:_ As typically implemented (by the routine of the same name in
the C library), this random number generator is a very poor one, though
the BSD and GNU libraries provide a much better implementation than the
`traditional' one.  On a different system you almost certainly want to
use something better.
