Explain the difference between defun and defun c

[David van Erk]

Hello,

Could somebody explain to me the significant difference between:
- DEFUN
- DEFUN C:
Any help would be much appreciated.

Thanks,

Really no significant difference, essentially the only difference is:

DEFUN - used for internal routines (helper routines used in other functions)

DEFUN C: - used for main functions that you want to call from the command line.

**EDIT**

Oh and when defined using DEFUN the function can accept arguments.

FYI..

Defun C: can be called with arguments also.

example

Command: (defun c:Test (string) (prompt string) (princ))
C:TEST

Command: (c:Test "\n Hello")

Hello
Command: test
; error: too few arguments
