Accessing Express Tool Commands

[sivampeta_dheeraj]

Can I know the philosophy behind the fact of using ((C:Express Tool Command);like (C:Layiso)) syntax to access the express tool commands from Autolisp.Instead of the general
(command "autocad command") structure.

Applies to all lisp routines. While "BURST" works on the command line, in BURST.LSP "(defun C:BURST" defines the function to lisp as "C:BURST". By placing "C:" in front of Burst it allows its use on the command line without the parentheses. For "(defun BURST" you would need to enter "(BURST)" on the command line.
