Display variable value within a text string when using an alert or princ

charlesc32 — Sat, 13 May 2023 04:01:07 GMT

Hello

I'm trying to display the value of a variable as the program runs through a While Loop. I need to see what it's picking up as my pgm reads through a Layer Table and I'm not sure which layer it has picked up before I can manipulate this information. Any ideas on How to do this?

Thanks in advance

assuming the variable is data then do this:

(alert (vl-princ-to-string data))

@charlesc32 hi,

how about this?

Moshe

(defun c:LWalk (/ tbl) (while (setq tbl (tblnext "layer" (not tbl))) (terpri) (princ (cdr (assoc '2 tbl))) ); while (princ) )

Hello Paul

Since this is a variable string coming from the layers table, I couldn't get your suggestion to work. Thank you for your response.

Regards,

Charles

Hello Moshe

Your suggestion worked nicely. Now I am able to track the input and decide how to approach each string within the program.

Thank you for your response,

Charles
