Everything I've done with varying variables is in free-form or EVAL

MOVE of a varying to fixed works as you'd expect.

But MOVE of a fixed to a varying, or a varying to a varying, doesn't necessarily work the way you'd expect. If you have a varying result field in the fixed-form opcodes that have a P=pad extender, the current length of the varying result field is not changed by the operation.

D fixedvar S 10A inz('1234567890')

D varyingvar S 10A VARYING
D INZ('abc')

c move fixedvar varyingvar

varyingvar will have the value '890' (3 bytes because it's value had been 'abc' before, and '890' because MOVE is a move-right).
