Users can now generate maps and tables with more than one .alist format. The standard format still works, but now airport codes can appear on different lines if the user chooses, allowing users to order airport visits by individual trip.
Example: this is the standard format for a user who traveled from PDX to DFW round trip:
PDX A D
DFW A D
However, using the new format will produce the same results:
PDX D
DFW A
DFW D
PDX A
In the past, the script rewrote the data for an airport every time it was encountered.
Thanks to si404 for suggesting this. Other suggestions are welcome.
