When buf2buf is not enough

When the global buf2buf is not enough! Copying two heterogeneous table buffers, but with practically the same field names.
Edit: Peter Chan beat me to it! The only advantage to using my function is an extra semi colon :)
Neither of our methods check to see if the field type is the same...

///Copy two different table buffers but with the same field names.
///May be better to use a Map...
static void bufFields2BufFields(
    Common  _from,
    Common  _to
    )
{
    DictTable   dictTableFr = new DictTable(_from.TableId);
    FieldId     fieldIdFr;
    DictTable   dictTableTo = new DictTable(_to.TableId);
    FieldId     fieldIdTo;
    FieldName   fieldName;
    ;
    fieldIdFr   = dictTableFr.fieldNext(0);
    fieldName   = dictTableFr.fieldName(fieldIdFr);
    fieldIdTo   = dictTableTo.fieldName2Id(fieldName);

    while (fieldIdFr && ! isSysId(fieldIdFr))
    {
        if (fieldIdTo)
        {
            _to.(fieldIdTo)     = _from.(fieldIdFr);
        }
        
        fieldIdFr           = dictTableFr.fieldNext(fieldIdFr);
        fieldName           = dictTableFr.fieldName(fieldIdFr);
        fieldIdTo           = dictTableTo.fieldName2Id(fieldName);
    }
}
