The BELOW ORACLE 10g statement displays "Bind Variable "C1" is NOT DECLARED"
How can I fix ?

declare
 A1 varchar := NULL;
 B1 varchar := NULL;
 C1 varchar := NULL;
begin
 Output_Type_Api.New__(:C1,:B1,:A1,'OUTPUT_TYPE' || CHR(31) || 'xxx' || CHR(30) || 'DESCRIPTION' || CHR(31) || 'xxx' || CHR(30),'DO');
END;

remove the colon
 Output_Type_Api.New__(C1,B1,A1,'OUTPUT_TYPE' || CHR(31) || 'xxx' || CHR(30) || 'DESCRIPTION' || CHR(31) || 'xxx' || CHR(30),'DO');

Not sure what your package Output_Type_Api.New does

I found that declaration is also not proper

Check declaration section below
declare 
 A1 varchar2(4000) := NULL;
 B1 varchar2(4000) := NULL;
 C1 varchar2(4000) := NULL;

Open in new window

A varchar variable cannot be declared without giving the size so give the size as shown in the eaerlier update by ajaexpert and also always use varchar2 instead of varchar even if it works for readability/simplicity as normally varchar2 is the one which should be used.

So try the attached code :

declare
 A1 varchar2(4000) := NULL;
--> change it to anything from 1 to 4000 but you need to ensure that the
-->value you are going to put inside this is not going to exceed the length
-->you have given here. otherwise you end up in value error due to variable
--> overflow.

 B1 varchar2(4000) := NULL;
 C1 varchar2(4000) := NULL;
begin
 Output_Type_Api.New__(C1,B1,A1,'OUTPUT_TYPE' || CHR(31) || 'xxx' || CHR(30) || 'DESCRIPTION' || CHR(31) || 'xxx' || CHR(30),'DO');  
--> also no need of : there as given in update by Zopilote in pl/sql.
END;

C1 is a local variable to the block and not a bind variable hence there is no need of column while using it and you need to put size while declaring the varchar variables.
DECLARE
  A1 VARCHAR2(4000) := NULL;
  B1 VARCHAR2(4000) := NULL;
  C1 VARCHAR2(4000) := NULL;
BEGIN
  Output_Type_Api.New__(C1,B1,A1,'OUTPUT_TYPE' || CHR(31) || 'xxx' || CHR(30) || 'DESCRIPTION' || CHR(31) || 'xxx' || CHR(30),'DO');
END;
If still the problem exists there must be some in calling your package Output_Type_Api.New__
