CAB Posted September 9, 2008 Share Posted September 9, 2008 Thanks CAB, Just out of interest, I have a few queries.... 1) (this may seem a little ignorant.. but I'm new to LISP) Why do you list your variables in the brackets after the (defun c:XXX ("here")... with a " / " ? 2) Why do you use the "vl-cmdf" instead of "command"? Thanks once again for your help. 1) to Localize the variables, it's good programing practice. 2) If you noticed the group of code wrapped in an AND function. This is done in order to execute each line of code until a nil return value. The nil return will stop execution of that sequence. In this case COMMAND always returns nil and I did not want the code to stop there so I could have wrapped the COMMAND in a (NULL to return T or the option I chose was to use a form of the command which does not return nil when properly executed. HTH, and glad you've got the code working. Quote Link to comment Share on other sites More sharing options...
