How to add or remove a trigger on an operator from within a user command?

I would like to have a user command that can add a couple lines of code to an operator's OnResourceAvailable trigger, and also remove the trigger. Currently there is no code on this trigger so there is no need to worry about it being overwritten. Similarly, when code is removed it can be removed all at once. I'm looking for a solution that works specifically via user command and not a process flow. It would also need to work while the model is running. Thanks in advance for your help.

Thanks @Jörg Vogel and @Matthew Gillespie! Here is a copy of the end result:

  1. /**Custom Code*/
  2.  
  3. // define Operator to consider
  4. string OpName = "Operator 1";
  5.  
  6. // identify the tree node for the operator in question
  7. treenode Operator = node(OpName,model());
  8.  
  9. // identify the tree node for the operator's OnResourceAvailable trigger
  10. treenode OperatorORATrigger = getvarnode(Operator, "onresourceavailable");
  11.  
  12. // define the run mode. commenting out the next line will delete the trigger
  13. var runmode = "add"; // add the trigger
  14.  
  15. // define a blank trigger code string
  16. string triggercode = "";
  17.  
  18. if (runmode == "add")
  19. {
  20.     // define code to be added to the operator's OnResourceAvailable trigger
  21.     triggercode = "/**Custom Code*/; pd(1); pr();";
  22. }
  23.  
  24. setnodestr(OperatorORATrigger,triggercode);
  25. buildnodeflexscript(OperatorORATrigger);

The Trigger is first of all a node which contains string data. That data is activated to be flexscript.

  1. setnodestr(getvarnode(centerobject(current, 1), "onresourceavailable"),"pr();pd(1);");
  2. buildnodeflexscript(getvarnode(centerobject(current, 1), "onresourceavailable"));

The centerobject is a Taskexecuter. I add the commands pr() and pd(1) to print a <CR> and "1" into the output console.
