Jim,

MOVEL does work with VARYING length fields.
When using MOVEL with VARYING length fields, the VARYING field's length
does not change. That is the VARYING length field's current length is
used, and hence the VARYING length field is treated as a fixed length
field whose length is the current VARYING field's length.

So a MOVEL of "BBB" to a VARYING length field whose current length is 5,
will replace the first 3 characters of the field. But a move of
"CCCCCCCCCC" to that same VARYING length field, would copy of "C"
characters to the field and the length would be unchanged.
