Hi Michell,
another to keep it saved with your cad program is to copy the lisp code in a text editor like notepad,
then from go to File---Save As and then from their name this file "yourfilename.lsp" whatever name you use, put the .lsp at the end.
then go to Autocad command line and type "appload"
A window will open, here select the saved lsp file and press load and , in Auto-cad command prompt it will show message "Loaded successful"
Now, go to command line and type the command go as in the program you can see " its written defun c:go (/ bl blname
Here in program whatever you will write after the C: as here it is go, you can write any command word which you remember, for example, "blocklistcreator""
It will run the loaded lsp program.
