Is there a way to query like this in Oracle 9i?

Question

Hi!
Before starting, some constraints: I can't use store procedures for this task, and should use ANSI99 wherever possible.
Let's suppose a table like this:
CREATE TABLE ELEMENTS
(REG_NAME VARCHAR2(10) NOT NULL, --PK
ELM_ORDER NUMBER(3,0) NOT NULL, --PK
ELM_NAME VARCHAR2(10) NOT NULL,
ELM_SIZE NUMBER(3,0) NOT NULL
It's a table describing some structures (REG_NAME), which contains elements (ELM_NAME) with the order number in register (ELM_ORDER) and its size (ELM_SIZE)
Some sample data '; ' separated fields, columns at first line:
REG_NAME; ELM_ORDER; ELM_NAME; ELM_SIZE
TYPE1; 1; VERSION; 3
TYPE1; 2; CALLNBR; 6
TYPE1; 3; DATE; 8
TYPE1; 4; EVENTTYPE; 4
TYPE1; 5; EVENTDESCR; 100
TYPE1; 6; EVENTCODE; 2
TYPE1; 7; ATTNAME; 10
TYPE2; 1; VERSION; 3
TYPE2; 2; CALLNBR; 6
TYPE2; 3; DATE; 8
TYPE2; 4; SOLCODE; 2
TYPE2; 5; SOLDESCR; 100
TYPE2; 6; ATTNAME; 10
I'd like to query the DB such way I could obtain:
VERSION 3 1 4
CALLNBR 6 4 10
DATE 8 11 19
EVENTTYPE 4 20 24
EVENTDESCR 100 25 125
EVENTCODE 2 126 127
ATTNAME 10 128 138
I.e, I need to obtain for an specific REG_NAME (TYPE1 in the sample query result), the columns ELM_NAME, ELM_SIZE of all rows in ELEMENTS table ordered by ELM_ORDER and the sum of ELM_SIZE of the previous rows + 1 and the same sum added by ELM_SIZE of the current row.
I'm almost sure there's a way to do that but I couldn't figure out how.
TIA,

If I understand your logic correctly, there are some calculation error in your sample result.
Don't know if this is possible using ANSI99, but in Oracle it is easy to do this:
SQL> CREATE TABLE ELEMENTS
  2  (REG_NAME VARCHAR2(10) NOT NULL, --PK
  3  ELM_ORDER NUMBER(3,0) NOT NULL, --PK
  4  ELM_NAME VARCHAR2(10) NOT NULL,
  5  ELM_SIZE NUMBER(3,0) NOT NULL
  6  );
Tabel is aangemaakt.
SQL> insert into elements values ('TYPE1',1,'VERSION',3);
1 rij is aangemaakt.
SQL> insert into elements values ('TYPE1',2,'CALLNBR',6);
1 rij is aangemaakt.
SQL> insert into elements values ('TYPE1',3,'DATE',8);
1 rij is aangemaakt.
SQL> insert into elements values ('TYPE1',4,'EVENTTYPE',4);
1 rij is aangemaakt.
SQL> insert into elements values ('TYPE1',5,'EVENTDESCR',100);
1 rij is aangemaakt.
SQL> insert into elements values ('TYPE1',6,'EVENTCODE',2);
1 rij is aangemaakt.
SQL> insert into elements values ('TYPE1',7,'ATTNAME',10);
1 rij is aangemaakt.
SQL> select elm_name
  2       , elm_size
  3       , sum(elm_size) over (partition by reg_name order by elm_order) - elm_size + 1 elm_size_2
  4       , sum(elm_size) over (partition by reg_name order by elm_order) + 1 elm_size_3
  5    from elements
  6   order by elm_order
  7  /
ELM_NAME                                 ELM_SIZE                             ELM_SIZE_2                     ELM_SIZE_3
VERSION                                         3                                      1                              4
CALLNBR                                         6                                      4                             10
DATE                                            8                                     10                             18
EVENTTYPE                                       4                                     18                             22
EVENTDESCR                                    100                                     22                            122
EVENTCODE                                       2                                    122                            124
ATTNAME                                        10                                    124                            134
