C Demonstrates the use make_sprng_seed
C 'make_sprng_seed' is used to produce a new seed each time the program is
C run. Then a few random numbers are printed.
C
program seedf_simple
implicit none
#define SIMPLE_SPRNG
#include "sprng_f.h"
integer seed, i, junk
SPRNG_POINTER junkPtr
real*8 rn
C---
integer gtype
#include "genf_types_menu.h"
print *,'Type in a generator type (integers: 0,1,2,3,4,5): '
read *, gtype
C---
C generate a new seed each time program is run and initialize stream
seed = make_sprng_seed()
junkPtr = init_sprng(gtype,seed,SPRNG_DEFAULT)
print *, 'Printing information about new stream'
junk = print_sprng()
print *, 'Printing 3 random numbers in [0,1):'
do 100 i = 1, 3
rn = sprng()
write(*,"(f8.6)") rn
100 continue
end
