Code:

<< 'KP' RCL 'KI' RCL 'KD' RCL -> kp ki kd << do something >> >>

Note that inside "do something", if you want to evaluate the local variables, you need to explicitly evaluate them, eg kp EVAL

I am not an expert in this field, but. If a global variable, say A, contain a number, array or a string then both ways (A and 'A' RCL) will give exactly the same result: load the value onto the stack.
If the global contains a program, say << do something >> then A would evaluate the program but 'A' RCL would give an error message.
So if Graan has numerical values or strings in KP, KI, KD then his program should work OK.
EDIT:
Oops, I was wrong 'A' RCL loads a program from A onto the stack as well (without evaluating it).
