The problem is that start_of_program event runs only once. The linked post start_of_program code will not be run without some deeper configuring. Also - the status of variables may not be appropriate either (as they were when the Cam generator started posting.) The linked post architecture writes over a bunch of procs - some are retained - some not. The master post has some extra ones (ex - the MOM_head one.) I think the easiest approach would be to copy the file at the point that start_of_program is done writing to the file path used for the linked post. This could be done by closing it, copying it then reopening it with TCL code as a last custom command in start_of_program. Use MOM_open_output_file and MOM_close_output_file (you probably already are) to redirect output and tcl command "file copy ...." to put the start_of_program code in the linked post file. I am not current with the linked post setup (code written to the tcl to manage it.) I started doing different kinematics from the same post. You may find that to be less trouble. Linked posts had some points of convenience for sure - but there was pain too.
