Just so I am sure I get it, an EVAL that sets a varying to the value of
a fixed, that gets the size of the fixed, right? This could include
trailing blanks, as I recall.

Right.

Now your MOVE example moved a longer value to a shorter. I assume that
for a MOVE, the length of the varying does not change, perhaps related
to the move-right. Is the original size maintained with a MOVEL, also?

Yes. The length of the varying result doesn't ever get changed by MOVE, MOVEL, CAT, SUBST, or XLATE. It doesn't matter whether the source is varying or fixed, or shorter or longer; the result length is the same after the operation as it was before. Basically, the varying length result field is temporarily treated as though it is a fixed-length field, so a varying field with a current length of 3 is treated the same as a field with a fixed-length of 3.

I don't recommend using MOVE, MOVEL etc with varying length result fields.
