The SORT function enables the user to sort a dynamic array, either left or right justified or into ascending or descending order. The general form of the function is similar to LOCATE( ):
Format
|
result=SORT(string{,attno{,valno}};sort.sequence) |
Description
If attno and valno are omitted, SORT( ) sorts the entire multiattribute list stored in string.
Sorting occurs according to the sort criteria specified by sort.sequence, which may be one of these:
|
AL |
Ascending, left justified |
|
AR |
Ascending, right justified |
|
DL |
Descending, left justified |
|
DR |
Descending, right justified |
If attno is specified, the sorted MultiValues of that attribute in the string are returned. Similarly, if valno is specified, only the multi-subvalues of the specified value is sorted and returned.
SORT( ) typically executes 5 to 10 times as quickly as other sorting routines in mvBASIC, and therefore should be used whenever speed is important.
