Need to store an ability's order string in a variable

Need to store an ability's order string in a variable

How can I go about doing this? I can't seem to find it in the gui triggers or in blizzard and common.j. Any help greatly appreciated!

You may save it as a string when:
1)hero learn an ability
2)Hero cast an ability
________________________
by GUI you can't do any others options

What is the command used to do this?

nevermind i just figured it out, which is exciting
