News flash: I'm going to Australia in February, so this Web site may be switched off at any time.
Icon's built-in ``sort()'' function can be used to
order the elements of a list. The expression
sort ( L )
returns a list with the same number of elements as L, except
they are sorted. This makes sense only for certain types---integers,
reals, and strings.
As an example, here is a program that writes the lines from its input in sorted order:
procedure main() lines := []; # Create an empty list while put ( lines, read ( ) ); # Store all lines every write ( ! sort ( lines ) ); # Sort and write endThe second line reads each input line and adds it to the list. In the third line, the expression ``
sort(lines)''
returns a list of the lines in sorted order; the ``!''
operator generates the lines from the sorted list in order, and
then they are written to the output.
