Passing Arrays to an SQL Call

I want to do this:

Exec Sql
Call PRMTEST(
:pInStore,
:pOtSKU);

Where pInStore and pOtSKU are arrays defined like this:

D pInSKU 9A Dim(200)
D pInQuantity 3A Dim(200)

And PRMTEST is an RPG program.

I'm getting an SQL0314 error in my compile. It's definitely due to the
array; if I take off the DIM it compiles.

I thought this was an issue in the past (passing arrays via a call
statement), but had been resolved by V7R1.

What do I need to do differently? I thought there was a thread about this
some time ago, but I can't find it. Thanks!
