getting buf2Buf by using x++ coding

This method takes two table buffers (from and To) as the parameter and copies the value from the Form Table Buffer to the To Table Buffer.

static void buf2BufByName(Common  _from, Common  _to)
{
    DictTable   dictTableFrom   = new DictTable(_from.TableId);
    DictTable   dictTableTo     = new DictTable(_to.TableId);
    DictField   dictFieldFrom;
    FieldId     fieldIdFrom     = dictTableFrom.fieldNext(0);
    FieldId     fieldIdTo
    ;
    while (fieldIdFrom && ! isSysId(fieldIdFrom))
    {
        dictFieldFrom   = new DictField(_from.TableId, fieldIdFrom);
        if(dictFieldFrom)
        {
            fieldIdTo = dictTableTo.fieldName2Id(dictFieldFrom.name());
           // info(dictFieldFrom.name());
            if(fieldIdTo)
                _to.(fieldIdTo) = _from.(fieldIdFrom);
        }
        fieldIdFrom = dictTableFrom.fieldNext(fieldIdFrom);
    }
}
