PL/SQL写的存储过程的参数传递问题！

[jyq686]

create or replace procedure exp_tShouPDJGL(
p_path varchar2,
p_filename varchar2,
p_begin_date tShouPDJGL.riq%type,
p_end_date tShouPDJGL.riq%type,
p_count out number,
p_txterr out varchar2)

如上过程，参数p_count和p_txterr是out型，目的就是要它在过程外面能输出一些提示信息，并且我也PL/SQL用dbms_output.put_line()过程能打印出这些信息。但是改用PB调用时就不行了，PB好像都不允许out型的参数存在。
这样少写两个out型参数在PB里能执行成功的，但却不能传递提示信息p_count和p_txterr了，

string path="D:\",filename="rjs14.txt",begin_date='20050310',end_date='20050310',txterr=""
int count=0
DECLARE exp_tshoupdjgl PROCEDURE FOR exp_fengs.exp_tshoupdjgl
(:path,
:filename,
:begin_date,
:end_date
)using sqlca;
execute exp_tshoupdjgl;

而如下写法在PB里根本就不能执行，提示参数的个数出错:
string path="D:\",filename="rjs14.txt",begin_date='20050310',end_date='20050310',txterr=""
int count=0

DECLARE exp_tshoupdjgl PROCEDURE FOR exp_fengs.exp_tshoupdjgl
(:path,
:filename,
:begin_date,
:end_date,
:p_count,
:p_txterr
)using sqlca;
execute exp_tshoupdjgl;
怎么解决啊？兄弟们，谢谢，分不够可以加！

string path="D:\",filename="rjs14.txt",begin_date='20050310',end_date='20050310',txterr=""
int count=0

DECLARE exp_tshoupdjgl PROCEDURE FOR exp_fengs.exp_tshoupdjgl
(:path,
:filename,
:begin_date,
:end_date
)using sqlca;
execute exp_tshoupdjgl;

fetch exp_tshoupdjgl into :p_count, :p_txterr;

存储过程定义
procedure prcgetleveldepth(p_tabname in varchar2,
p_fieldid in varchar2,
p_filedname in varchar2,
p_leafcond in varchar2,
p_leveldepth out number) is
pb中的调用
DECLARE AAprcgetleveldepth PROCEDURE FOR
prcgetleveldepth(p_tabname => :ls_tabname,
p_fieldid => :ls_fieldid,
p_fieldname => :ls_fieldname,
p_fieldparent => :ls_parent,
p_leafcond => :ls_leafcond);

EXECUTE AAprcgetleveldepth;
if SQLCA.SqlCode <> 0 then
Messagebox("错误提示","获取深度失败！")
RETURN
end if

fetch AAprcgetleveldepth into :li_leveldepth;
Close AAprcgetleveldepth ;
