qsort(3F)

NAME
     qsort - quick sort

SYNOPSIS
     subroutine qsort (array, len, isize, compar)
     external compar
     integer*2 compar

DESCRIPTION
     One dimensional array contains the elements to be sorted.  len is the
     number of elements in the array.  isize is the size of an element,
     typically -

          4 for integer and real
          8 for double precision or complex
          16 for double complex
          (length of character object) for character arrays

     Compar is the name of a user supplied integer*2 function that will
     determine the sorting order.  This function will be called with 2
     arguments that will be elements of array. The function must return -

          negative if arg 1 is considered to precede arg 2
          zero if arg 1 is equivalent to arg 2
          positive if arg 1 is considered to follow arg 2

     On return, the elements of array will be sorted.
