Acept a variable and interact with messages boxes

[SCaldeira]

I have a repetitive procedure instaledon Autocad in my office that consists of:

-Accept a point of avariable PTN.

-Click on a Yes button on a existing messagebox.

-Click on a Ok button on a existing message box.

Toexecute the aplication i need put on prompt (C:CARTO) and then heask me for a point and I have a variable called PTN with thepretended value. Then, two messages box appearing and I must do entertwice. I need a simple loop to run CARTO, accept PTN and confirmtwice on the messages boxes.

How can I simplify this inAutolisp?

Excuse my bad English.

Thank you.
