SLASRT sorts numbers in increasing or decreasing order.
Function/Subroutine Documentation
subroutine slasrt (characterID, integerN, real, dimension( * )D, integerINFO)
SLASRT sorts numbers in increasing or decreasing order.
Purpose:

Sort the numbers in D in increasing order (if ID = 'I') or in decreasing order (if ID = 'D' ). Use Quick Sort, reverting to Insertion sort on arrays of size <= 20. Dimension of STACK limits N to about 2**32.
Parameters:

ID
ID is CHARACTER*1 = 'I': sort D in increasing order; = 'D': sort D in decreasing order.
NN is INTEGER The length of the array D.
DD is REAL array, dimension (N) On entry, the array to be sorted. On exit, D has been sorted into increasing order (D(1) <= ... <= D(N) ) or into decreasing order (D(1) >= ... >= D(N) ), depending on ID.
INFOINFO is INTEGER = 0: successful exit < 0: if INFO = i, the ith argument had an illegal value
