Urgent:How to manipulate the below problem

Question

I am dynamically writing a PL/SQL blok. as follows--
problem areas marked in bold.
     l_statement :=
' DECLARE'                                    ||
'      TYPE record_type IS RECORD ('          ||
          Col_Desc_Pkg.record_defn || ');'     ||
'      l_record record_type;' ||
'      l_ref_cur Col_Desc_Pkg.CURSORTYPE;' ||
'     rec_count NUMBER;                    '     ||
'     dcl_stmt VARCHAR2(32000);          '     ||
'     dml_target_insert VARCHAR2(5000);'     ||
'     l_temp_var          varchar2(100);'     ||
' BEGIN' ||
' l_ref_cur := NewDataCleanUp.REF_CUR;'      ||
' LOOP' ||
' FETCH l_ref_cur INTO l_record;'      ||
' EXIT WHEN l_ref_cur%NOTFOUND;'      ||
'     dcl_stmt := '' '||Create_Dcl_Stmt(TargetT)||' '';'|| --My problem area
'           DBMS_OUTPUT.PUT_LINE(dcl_stmt); ' ||
' END LOOP;' ||
' CLOSE l_ref_cur;' ||
' END;';
FUNCTION Create_Dcl_Stmt(TargetT VARCHAR2) RETURN VARCHAR2 IS
l_dcl_stmt VARCHAR2 (5000);
l_col_name VARCHAR2(50);
counti     NUMBER;
BEGIN
     l_dcl_stmt := ' SELECT COUNT(1) FROM '||TargetT||' T WHERE T.';
     FOR counti IN 1..g_Column_Name_Arr.COUNT LOOP
          l_col_name := g_Column_Name_Arr(counti);
(M1)     l_dcl_stmt := l_dcl_stmt||l_col_name||' =''l_record.col_'||counti||'||'' AND T.'; (/M1)          
     END LOOP;
     l_dcl_stmt := RTRIM (l_dcl_stmt, 'AND T.');
     l_dcl_stmt := l_dcl_stmt||';';
     RETURN l_dcl_stmt;
END;
now when i execute the aboove i get the query as below
SELECT COUNT(1) FROM HIST_PORTS_MASTER T WHERE T.PORT_ID =1041 AND T.PORT_STATUS =processed;
but i want that each of the values be enclosed in singke qoutes as T.PORT_ID ='1041' .
Trying to edit line M1 does not work. The value 1041 comes when the ''l_record.col_'||counti||'||'' is dynamicaly executed. how do i put single quotes around a value already in single quotes.??????

By doubling / tripling... them. Play around with your erroneous part of the string. You'll get a feeling for it.
