	I'm trying to write code that copies an array (created by a UDO) to an array within another array. That is, given an array or arrays thus gi_ary[][] init 30, 128 I would like to be able to assign/copy to the "inner" arrays. for example gi_ary[0] = my_udo(...) where "my_udo" returns an array. However, I get this: error: Unable to find opcode entry for '=' with matching argument types: Found: i = k[] I've attached an example.

	FWIW, using setrow() instead of "=" gives the same error.

	There's an issue here about gi_array[0] being reported as an i-type, but regardless your idea to assign a one dimensional array to the area within a two dimensional array shouldn't work. Multidimensional arrays are different from a list of lists and it seems like you're thinking more the latter than the former. (For example, see the conversation here: https://stackoverflow.com/questions/40895721/python-is-a-multidimensional-array-matrix-the-same-thing-as-lists-within-li). I don't know if we can do something to address making something like this possible with some checks for matching dimensions but as it stands now it's not possible. Regarding setrow(), I would expect that to work though I'm not sure if it would using function-call syntax (not sure of its implementation). What code did you use to test that?

	I am currently using tables instead of arrays. Since I can't have array pointers in csound, I'm using tables instead. I can create and destroy tables at will (like with new and free in c ++), and therefore load and change different projects without leaving csound, because I don't need to know their sizes in advance. Also, with tables, I don't need to know if my data is irate or krate. And instead of table arrays, I am using tables of tables. Am i wrong?

	Nothing wrong with that whatsoever. I just have a slight preference for arrays, because (as a programmer) I find array syntax -- my_array[1] -- more intuitive than table syntax -- table(0, my_table). Tables work great. But variable rate does matter depending on context -- sometimes I can use table(), sometimes I need to use tablekt() (for example).
