change color line with autolisp

[Angelo2449]

Hello everyone,
I do not find the instruction with which to set the color and type of line before tracking it.
Of course by autolisp:
- I choose the color
- I choose the line type (tracked, continuous, etc.)
- I draw the line
...... .
- I choose the color
- I choose the line type (tracked, continuous, etc.)
- I draw the line
...... .
Thank you.

you have to set two variables
♪
celtype

(setvar "cecolor" 1); draws in red
(setvar "celtype" "hidden")
