Yes, that is pretty much what I wanted.
Thanks.

Let
a=: 'a'
b=: 'b'
c=: 'c'
and let
arr=: a;b;a;c;b;c;a;b;b;b;c;a;b NB. i.e. all items from a,b,c
I want to relabel the items
with
e=: 'e'
f=: 'f'
g=: 'g'
so a -> e, b -> f, c -> g.
so arr becomes
e;f;e;g;f;g;e;f;f;f;g;e;f
Is there a succinct (preferably tacit) way to do this?
I feel like
