Special Unit Movement Question

I'm trying to do the following: move the unit onwards accordingly to its facing angle. For example, a unit with facing angle 0 will move foward when triggered. The facing angle, in this case, will vary. I'm expecting to set a button the change the unit's facing angle and another to trigger the movement action down. How do I do that? Is there other way rather than setting points? I also want to save the unit's destination on a variable.

Thanks for all help

Unit - Order (Last created unit) to Move To ((Position of (Last created unit)) offset by 500.00 towards (Facing of (Last created unit)) degrees)

Set Variable = (Facing of (Last created unit))

Great! Thanks for help.
