Definition

This function sorts the list specified and returns the sorted list. The sort method can be specified with the optional subroutine or block argument. A subroutine may be specified that takes two arguments (passed as global package variables, $a $b) and returns TRUE if the first is less than or equal to the second by any criteria used. Similarly, a block can be specified (effectively an anonymous subroutine) to perform this function. The default sort order is based on the standard string comparison order.

Example

@a = ("z","w","r","i","b","a");
print("sort() ",sort(@a),"\n");
