Ref: Your note of Fri, 18 Jan 2013 19:54:13 +0000 If you want to modify DC, you need to define an opcode which refers to the original DC first so that you can invoke it from within the macro.
DC_ OPSYN DC Set up alias for original DC
DC OPSYN MYDC Redirect DC to my macro
Then within the macro you can use
DC_ &whatever Issue real DC
