unit codes

How do I see the unit codes of custom units?

Create a trigger with your unit and convert to custom text.

Does that work when I do a spell? can I make a spell that summons a custom unit?

Yes, but remember that unless you copy the unit data it will only be relative to that particular map.

and how do I copy the unit data to another map?

in the unit edit, save the units, open up a new map, and import it.

Note: this only works on the standard units and NOT custom units

Actually it works fine for custom units as well. If you import the unit stats and then open the mpa you imported from and then reopen the map you imported to the custom unit stats should have loaded. Actualy you just need to open any map then reopen the map you imported to and the unit stats for custom units will be there. A strange blizzard glitch I geuss.
