Converting old SQL Server outer join syntax

I'm a Power Builder (PB) developer. I've migrated PB from 10 .5 to 12.5, and now I need to migrate the stored procedures from SQL Server 2005 to 2012 as well.

I get a invalid expression error when I run the procedures in Power Builder. We have previously been using a lower database compatibility model in 2005, which allowed the procedures to work there. I have learned that =* is the old way to write right outer joins.

For example:
select  *
from    A
right outer join
        B
on      A.bid = B.id

...is written in the old style like:
select  *
from    A,
        B
where   A.bid =* B.id

Here is a part of my procedure that uses *=:
SELECT  DISTINCT  
   a_stmt.cyc_dte,  
   a_carr.carr_nm,  
   a_stmt.amt_du_ic  
 FROM  a_stmt,  
   s_dataccs,  
   a_carr,  
   a_icc  
 WHERE ( a_stmt.ic_cntct_id *= a_icc.ic_cntct_id ) and  -- HERE
   ( a_icc.usg_ind = 'S' ) and  
   ( a_carr.acna = a_stmt.acna ) and    
   ( s_dataccs.acna = a_stmt.acna ) and ( s_dataccs.user_id = @user_id ) and  
   ( ( a_stmt.acna = @acna ) or ( @acna = '' ) ) AND    
   ( ( a_stmt.juris_id = @juris_id ) or ( @juris_id = '' ) ) AND    
   ( a_stmt.jrnl_mo_yr = @jrnl_mo_yr ) AND  
   ( a_stmt.amt_du_ic < 0 )

I have converted that to:
SELECT  DISTINCT  
   a_stmt.cyc_dte,  
   a_carr.carr_nm,  
   a_stmt.amt_du_ic  
from
a_stmt left outer join a_icc on a_stmt.ic_cntct_id = a_icc.ic_cntct_id
 join  a_carr on a_stmt.acna = a_carr.acna join s_dataccs on a_stmt.acna = s_dataccs.acna and
   ( a_icc.usg_ind = 'S' ) and  
   ( s_dataccs.user_id = @user_id ) and  
   ( ( a_stmt.acna = @acna ) or ( @acna = '' ) ) AND    
   ( ( a_stmt.juris_id = @juris_id ) or ( @juris_id = '' ) ) AND    
   ( a_stmt.jrnl_mo_yr = @jrnl_mo_yr ) AND  
   ( a_stmt.amt_du_ic < 0 )  


Here is one more :
SELECT r_rj.juris_id, "GRAND TOTAL", "",  
round( isnull (sum(a_ovrudr.bd_intl + a_ovrudr.bd_inter + a_ovrudr.bd_intra+  
a_ovrudr.bd_fed_tx + a_ovrudr.bd_st_lcl_tx), 0), 2),    
r_rj.ord    
FROM a_ovrudr,            r_rj    
WHERE ( a_ovrudr.juris_id =* r_rj.juris_id) and  
( a_ovrudr.acna = @acna  ) AND    
(( SUBSTRING (a_ovrudr.jrnl_mo_yr, 3,4) = @yr_1 ) OR  
( SUBSTRING (a_ovrudr.jrnl_mo_yr, 3,4) = @yr_2 )  OR  
( SUBSTRING (a_ovrudr.jrnl_mo_yr, 3,4) = @yr_3 ) OR  
( SUBSTRING (a_ovrudr.jrnl_mo_yr, 3,4) = @yr_4 ) OR  
( SUBSTRING (a_ovrudr.jrnl_mo_yr, 3,4) = @yr_5 ) )    
GROUP BY   a_ovrudr.acna,  r_rj.juris_id, r_rj.ord  
ORDER BY  yr, mo, r_rj.ord

which I have converted as :
SELECT r_rj.juris_id, "GRAND TOTAL", "",  
round( isnull (sum(a_ovrudr.bd_intl + a_ovrudr.bd_inter + a_ovrudr.bd_intra+  
a_ovrudr.bd_fed_tx + a_ovrudr.bd_st_lcl_tx), 0), 2),    
r_rj.ord    
FROM a_ovrudr right outer join r_rj on a_ovrudr.juris_id = r_rj.juris_id and  
( a_ovrudr.acna = @acna  ) AND    
(( SUBSTRING (a_ovrudr.jrnl_mo_yr, 3,4) = @yr_1 ) OR  
( SUBSTRING (a_ovrudr.jrnl_mo_yr, 3,4) = @yr_2 )  OR  
( SUBSTRING (a_ovrudr.jrnl_mo_yr, 3,4) = @yr_3 ) OR  
( SUBSTRING (a_ovrudr.jrnl_mo_yr, 3,4) = @yr_4 ) OR  
( SUBSTRING (a_ovrudr.jrnl_mo_yr, 3,4) = @yr_5 ) )    
GROUP BY   a_ovrudr.acna,  r_rj.juris_id, r_rj.ord  
ORDER BY  yr, mo, r_rj.ord







Is my approach correct, or do I need to add a WHERE condition to it? I don't have access to the production database to check. The development database is in SQL Server 2012 too, sO I will not be able to run the old version there to check. It would be really kind, if someone could help me out with this!
