Selection & Custom Menu's

Hi Guys & Girls

Have a few selection problems. (Sorry I'm an Autocad LT user)

1 - Need to draw a line in a macro and then later select the start & endpoint of the same line. $(getvar,lastpoint) works for the last point but cannot select the first point. Any ideas?

2 - Need to select;last; when using the measure command but does not work. Any ideas? Is there a deisel command that will do this for me?

3 - Want to create drop down menu that swaps contents depending on top level menu serection. What code do I use? See below example.

My Meny

'Menu A'

Menu B

Menu C

a-1

a-2

a-3

a-4

I know how to do flyout secondary menu's but not swap menu's. Any Ideas?
