12 CHARACTER ID

14 INTEGER INFO, N
15
16 REAL D( * )
17
19 Sort the numbers in D in increasing order (if ID = 'I') or in decreasâ
20 ing order (if ID = 'D' ). Use Quick Sort, reverting to Insertion sort
21 on arrays of
22 size <= 20. Dimension of STACK limits N to about 2**32.
23
25 ID (input) CHARACTER*1
26 = 'I': sort D in increasing order;
27 = 'D': sort D in decreasing order.
28
29 N (input) INTEGER
30 The length of the array D.
31
32 D (input/output) REAL array, dimension (N)
33 On entry, the array to be sorted. On exit, D has been sorted
34 into increasing order (D(1) <= ... <= D(N) ) or into decreasing
35 order (D(1) >= ... >= D(N) ), depending on ID.
36
37 INFO (output) INTEGER
38 = 0: successful exit
39 < 0: if INFO = -i, the i-th argument had an illegal value
