Using the command erase

Hello

Why is it that when I use the command in (command "erase" (entlast)) it selects the entity but does not erase it (is still in mode select) and if I use (command "erase" (entlast) "") the program erases the entity but ends up by crashing giving me the message "bade argument type" while it is still in mode select.

Thank you

(command "erase" (entlast) "") is correct, what is the next part of code doing ?

Thank you for your answer. yes I made a mistake in my coding , I found it by going through my coding step by step by inserting (princ 1) , (princ 2).... between each line of code, and found where it was failing. Is there a way of doing this automatically ?

I just copy and paste each line to command line sometimes but there is a bit of an art to doing this pasting multiple lines. Use Vlide and make sure DEBUG break on error is ticked on, then use the "last break source" helps to show which line, you can also check variables values looking for Nil by using "View inspect"

You can also step 1 line at a time. Others like Lee-mac will give you far better advice about using Vlide than me.
