Most of the question's above. I shall be running a campaign tomorrow where thieves and traps may have a higher profile than usual, and it occurred to me to wonder whether the thief skill of "find/remove traps" (FRT) means "find or remove traps" or "find and remove traps". That is, does Lemmy Lightfingers have to make his FRT roll once to find a trap, then a second time to disarm-without-tripping it; or does the one successful roll do it all for him? If you think it's the latter, what happens in the case of failure (does he fail to find, or find-but-fail-to-remove-safely)?
I'm most interested in canon statements from 1e, since I can't find anything yet; failing that, I'd be very pleased to hear reasoned arguments. Rules quotations from other games, including later editions of D&D, aren't so useful to me.
Thanks for any light anyone can shed.
Edit: when I raised this, one of my powergamers - with just the tiniest amount of raised eyebrow - pointed out that the English edition 1e PHB is clear about this on p.28:
Roll for each function separately (a trap must be located before removal can be attempted).
However, it's unclear about what happens when you fail the remove roll, and several of you have provided the excellent suggestion that you just can't remove it, except on a 96-00, when you trigger it.
So thank you all. I shall accept M.C.'s answer because it's closest to the authoritative, contemporaneous 1e reference that I'd asked for; but any of your answers would have been enough, and they're all excellent; I'm sorry not to be able to accept them all.
