Modify system function in 50g

[3298]

Such a vague request from you, again ... of course the answer is: it depends.

If all you want to do is edit a copy of some system routine, do what you would do with your own variables: recall and edit. Recalling the system routines is a bit more tricky than your variables, but come on, I know you've done it before - when you used Nosy.

Overwriting the original, however, is basically impossible.
