Sorry, I accidentally deleted part of the mail
the “where and why” part is mostly lost.
it also dealt with using /~ and
why it’s no use in this case
(monadic/dyadic meanings of ~);
and the function definition is lost, too.
I’ll only repeat that one:
f =: ,/"1 0
1 2 7 f 30 40
I recommend looking up ~ as well

Or, starting from your first approach,
teaching where and why it failed:
1 2 7 ,/"1 0 ] 30 40
you want ,/ to work on a list on the left
and individual atoms on the right
" (rank) does that. It tells the verb
(,/ in this case) to apply to lists (1)
on the left and atoms (0) on the right.
Thus ,/"1 0 does it.
] in effect only separates the list argument 1 0
for " from the list argument 30 40 to ,/"1 0
look up rank (both the concept and the verb ")
