      <description>&lt;P&gt;is there a good guide to getting started in LISP on the MAC side. I am lost LOL.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;I have a ton of old Lisp routines &amp;nbsp;I wrote or modified several years ago and I started with a simple one that should add a plot date and time to a drawing. all I get back from AutoCAD is "error: malformed list on input". any input would be welcome. this is not a required thing for me but I just started here as it seamed like a simple starting place&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;DIV&gt;; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp;Stamper - &amp;nbsp;Date/Time Stamp your drawings&lt;/DIV&gt;&lt;DIV&gt;;______________________________________________________&lt;/DIV&gt;&lt;DIV&gt;&amp;nbsp;&lt;/DIV&gt;&lt;DIV&gt;(defun C:STAMPER ()&lt;/DIV&gt;&lt;DIV&gt;(Prompt "\nSTAMPER -DATE/TIME Stamp your Drawings")&lt;/DIV&gt;&lt;DIV&gt;;&lt;/DIV&gt;&lt;DIV&gt;;&lt;/DIV&gt;&lt;DIV&gt;(setq OLD_CMDECHO (getvar "CMDECHO"))&lt;/DIV&gt;&lt;DIV&gt;(setvar "CMDECHO" 0)&lt;/DIV&gt;&lt;DIV&gt;(Prompt "\nPlease wait while the stamp is updated")appload&lt;/DIV&gt;&lt;DIV&gt;;&lt;/DIV&gt;&lt;DIV&gt;(setq TEXT_ENTITY (ssget "x"(list(cons 0 "TEXT")(cons 62 7))))&lt;/DIV&gt;&lt;DIV&gt;;&lt;/DIV&gt;&lt;DIV&gt;(if(Null TEXT_ENTITY)&lt;/DIV&gt;&lt;DIV&gt;(progn&lt;/DIV&gt;&lt;DIV&gt;(Prompt "\nSTAMP not found, creating it...")&lt;/DIV&gt;&lt;DIV&gt;(command ".TEXT" ".25,.25" 0.1 90 "STAMPER")&lt;/DIV&gt;&lt;DIV&gt;(setq TEXT_ENTITY (entlast))&lt;/DIV&gt;&lt;DIV&gt;(prompt "Complete.\n")&lt;/DIV&gt;&lt;DIV&gt;)&lt;/DIV&gt;&lt;DIV&gt;)&lt;/DIV&gt;&lt;DIV&gt;(setq DATE_TIME (rtos (getvar "CDATE") 2 8))&lt;/DIV&gt;&lt;DIV&gt;(setq MONTH (substr DAT_TIME 5 5))&lt;/DIV&gt;&lt;DIV&gt;(setq DAY (substr DATE_TIME 7 2))&lt;/DIV&gt;&lt;DIV&gt;(setq YEAR (substr DATE_TIME 3 2))&lt;/DIV&gt;&lt;DIV&gt;(setq HOUR (substr DATE_TIME 10 2))&lt;/DIV&gt;&lt;DIV&gt;(setq MINUTE (substr DATE_TIME 12 2))&lt;/DIV&gt;&lt;DIV&gt;(setq NEW_STRING&lt;/DIV&gt;&lt;DIV&gt;(strcat "SENT TO PLOTTER ON "YEAR"/"MONTH"/"DAY"/" at "HOUR":"MINUTE")&lt;/DIV&gt;&lt;DIV&gt;)&lt;/DIV&gt;&lt;DIV&gt;(command ".change" TEXT_ENTITY "" "" "" "" "" "" NEW_STRING)&lt;/DIV&gt;&lt;DIV&gt;(command ".chprop" TEXT_ENTITY "" "C" 7 "LA" 0"")&lt;/DIV&gt;&lt;DIV&gt;(setvar "CMDECHO" OLD_CMDECHO)&lt;/DIV&gt;&lt;DIV&gt;&amp;nbsp;&lt;/DIV&gt;&lt;DIV&gt;(prompt "Proigram Complete"&lt;/DIV&gt;&lt;DIV&gt;(princ)&lt;/DIV&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;</description>

      <description>&lt;P&gt;Welcome to Autodesk Forums!&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;Hi&amp;nbsp;&lt;a href="https://forums.autodesk.com/t5/user/viewprofilepage/user-id/10619536"&gt;@tkollarAB2B9&lt;/a&gt;&amp;nbsp;,&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;There are some errors in your code.&lt;/P&gt;
&lt;P&gt;Try attached LSP. You&amp;nbsp;can compare it with yours.&lt;/P&gt;</description>
