SORT

The SORT function returns a vector of subscripts that allow access to the elements of Array in ascending order. The result is always a vector of longword type with the same number of elements as Array .

Calling Sequence

Result = SORT( Array )

Arguments

Array

The array to be sorted. Array can be any basic type of vector or array. String arrays are sorted using the ASCII collating sequence. Complex arrays are sorted by their magnitude.

Example

To illustrate, assume the vector A contains the elements [4, 3, 7, 1, 2]. Then:

SORT(A) = [3, 4, 1, 0, 2]

because:

A[3] < A[4] < A[1] < A[0] < A[2]

To see the elements of A in sorted order use the expression enter:

PRINT, A(SORT(A))

which prints:

1 2 3 4 7

To obtain the elements in descending order enter:

PRINT, A(REVERSE(SORT(A)))
