line marker

[joe]

good morning, I would like to make sure, by means of a lisp, to assign to each line an id type " a1, a2, a3, a100 etc., through of course the selection and that it is inserted at the beginning or little more than the line.
Is it possible?
thanks to availability

by "id" do you mean a text placed above the line?
If so you could simply make a block with attribute, in which the attribute is the text (which you can vary to each inserted block), while for the line you make a long line 1 (1 design unit) .... and then climbing the block you get the desired length.
