Problems using REPLACE on 10g

Question

Hello everyone,
I'm having a big problem that I can't figure out why ...
look at the following select that is executed ok...
SQL> select max(cgc) from clientes;
MAX(CGC)
999.984.838-91
but when I use replace, on the following select, Oracle extends the line that separats the header from the data....look
SQL> select REPLACE(REPLACE(REPLACE(CLIENTES.CGC,'.',''),'/',''),'-','')
2 from clientes;
REPLACE(REPLACE(REPLACE(CLIENT
61235123000104
94406790000153
88626098000138
12272753000720
30333686000101
96494042000103
23282150172
01814062000108
05923334000150
33013137000130
REPLACE(REPLACE(REPLACE(CLIENT
00123077000159
06110864000142
why does Oracle insert more "-" just above the first row????
and then on delphi 5 it "guess" that the column isn't varchar2(1 as it is, it "guesses" that the column is MEMO.
I tried as well substr and format as you can see below
SQL> select substr(REPLACE(teste.aaa,'l','p'),1,2) as teste_replace from teste;
TESTE_REPLACE
aa
Tim, the format doesn't work as well, I'm sure it seems to be a parameter or a enviroment configuration, take a look..
SQL> col aaa for a3
SQL> select replace(teste.aaa,'a','7') from teste;
REPLACE(TESTE.AAA,'A','7')
77l
And if I connect to another instance, on the same sql plus, look
SQL> conn fernando/*****@oracle2004
SQL> select replace(teste.aaa,'a','7') from teste;
REP
771
It works, I'm wondering which configuration could be....
Anyone can please help me out ?
Cheers

cursor_sharing
SIMILAR
SQL> select table_name from dict where rownum = 1;
TABLE_NAME
ALL_ALL_TABLES
SQL> select replace(table_name, '_', ' ') from dict suspect_cursor_sharing where rownum = 1;
REPLACE(TABLE_NAME,'_','')
ALL ALL TABLES
SQL> select sql_text from v$sqlarea where lower(sql_text) like '%suspect_cursor_sharing%';
SQL_TEXT
select replace(table_name, :"SYS_B_0", :"SYS_B_1") from dict suspect_cursor_sharing where rownum = :"SYS_B_2"With bind variables Oracle can not distinguish maximum length of string after replace. So it treat such expresions as varchar2(4000)
