Thanks. But it now fails with length error when calling numerize with a

If you break down what's happening inside the function with your example:
1 2{arg
+------+-+
|266239|1|
+------+-+
>1 2{arg
266239
1
".>1 2{arg
266239 1
So this vector gets boxed and put into both places. If you allow for
multiple elements in "x", you might do something like this:
(".&.>1 2{arg) (1 2)}arg
+-----+------+-++
|ALPHA|266239|1||
+-----+------+-++
So,
numerize =: 13 : '(".&.>x{y)(x)}y'
([: {. 0 $ ]) &.> 1 2 numerize arg NB. Show 0 for numeric, ' ' for
character arguments.
+-+-+-+-+
| |0|0| |

I have this little function:
numerize =: 13 : '(<".x{>y)x}y'
It makes numeric the contents of the xth box of the y argument. For
example, let b:
b
┌─────┬──────┬─┐
│ALPHA│266239│1│
└─────┴──────┴─┘
1 numerize b makes numeric the middle box.
Why does it not work with the last two elements of b, namely:
1 2 numerize b
but instead inserts a 2.element vector in each of the boxes 1 and 2?
Thanks.
