David:

You mentioned that the fields were defined as variable-length, but you didn't 
describe what you assigned as allocated-length. If allocated length is equal to 
field-length, then each field will pfysically end up being two bytes longer 
than an equivalent fixed-length field.

Try with an allocated-length of 1 or 5 or 10, then report back with results.

Note that allocated length is set by VARLEN(alc_len).
