Thanks everyone for responding.

It seems it turned out to be not as simple as I thought but I have
settled on a method. Without testing it yet, I have settled on the
following code:

values_2_remove = (huge_array[groupidx])
[indices_2_remove_in_group_array]
nvalues = N_ELEMENTS(values_2_remove)
full_idx = INTARR(nvalues)

FOR k=0, nvalues-1 DO full_idx[k] = WHERE(huge_array EQ
values_2_remove[k])

REMOVE, full_idx, huge_array

In general, the items to remove is quite small (~30) so I am content
with using the for-loop for cleanliness. And for my purposes the
WHERE function will always return only 1 value. If anyone has any
further suggestions on how to do this better, feel free to post, I'd
love to know =)

I didn't know that through all of this I would be able to learn so
much about the magic of IDL =)

Thanks Again,
Ryan.
