In this case, you don't even have to use amend. Just use something like this.
d =: ' 5\ 3\2004' NB. btw, why the backslashes instead of slashes?
is that some national spelling?
(' '&= {"0 1 ,.&'0') d
05\03\2004
(' '&= { ,&'0')"0 d
05\03\2004
In fact, you could also use item amend instead of index like this, but
I keep forgetting how that works. Looking up in the dictionary gets
me this.
(' '&=@:])`(,:&'0')} d
05\03\2004
Then there's a somewhat strange solution of using power.
'0'"_^:(' '&=)"0 d
05\03\2004
You could even use agenda similarly to this, but using agenda when
just indexing also works seems like a waste even though it's often
easier to write.
