Note that the "c:" prefix has no bearing on whether or not the function may accept arguments - _$ (defun c:foo ( x ) (+ x 2)) C:FOO _$ (c:foo 2) 4 The "c:" prefix is solely use to make a function available as a command which may be executed directly at the AutoCAD command line. Of course, evaluating a function which requires arguments as a command directly at the command line will result in a "too few arguments" error, but these two properties of a function are not related.

You may wish to refer to my explanation here.

In addition to @rkmcswain excellent answer above, look at these two functions, and spot the differences (defun function_name (passed vars / local_vars) expressions ) (defun C:function_name ( / local_vars) expressions )

[SEE COLON] simply means that the function name following can be used at the command line, like a core function (i.e.: Line, Circle, Pline). If you omit the prefix, or use your own like KW:Fun, then you have to include that part when you call the function name, along with enclosing it in parenthesis (KW:Fun) Some authors do this to their functions for identification purposes.

While you're waiting, consider that this isn't some magic portal where you ask for something for free and it's delivered to you with a flash of smoke.....

Wouldn't it be wiser to use the default browser? (command "_.Browser ...)
