In dscribe, let's say you'd like to read in a 3D lattice from a plain
file with no header. Therefore, you'd like to enter xdim, ydim, and zdim
from parameters.

Next, you need to pass xdim, etc into the dims of the output lattice. 
Problem is, the parameters are three scalars, and the dims is an array.
I tried making subregions of the dims array (from 1 to 1, 2 to 2, 3 to 3),
but dscribe treats them as arrays even though there's only one component.

Is there a way around this? Is this fixed somehow in Explorer 2? When is
Explorer 2 due out?

Thanks a lot.

There are a couple ways to do this. 

Bring up a Constants template and put a set in it. Put 3 longs in it
and give the initial values to be the parameter variables. Then connect the
set to the dims array.

Like:

  Parameter
	Long 1	| xdim
	Long 2 | ydim
	Long 3 | zdim

  Constants
	Set
	  Long 4   | dumx  | xdim
	  Long 5  | dumy  | ydim
	  Long 6  | dumz  | zdim

where {x,y,z}dim are the parameters 
-----

Or you can go to the dims array and make fragments and wire to them
And ignore the warning msg at Parse time about scalar connected to Array.
