Calling stored procedure from a stored procedure

Question

I have a stored procedure that accepts a customer prefix like "abc" and returns a customer document number like "abc-0021". (Thanks V Garcia)
This sp works when I call it from SQL Plus Worksheet.
But I need to call it from another stored procedure and store it in a local variable so that I can insert it into a table with the rest of the information.
This is what I have tried so far:
CREATE OR REPLACE  PROCEDURE "SCHEMANAME"."SP_XXTESTXX" ( seq_name in
    varchar2)
AS
      id_out varchar(10);
BEGIN
   execute SP_GET_NEXT_DOC_NUMBER(seq_name,:id_out);
   print id_out;
END;but this will not compile. I get this error:
Line # = 8 Column # = 12 Error Text = PLS-00103: Encountered the symbol "SP_GET_NEXT_DOC_NUMBER" when expecting one of the following:     := . ( @ % ; immediate The symbol ":=" was substituted for "SP_GET_NEXT_DOC_NUMBER" to continue.
Line # = 8 Column # = 41 Error Text = PLS-00049: bad bind variable 'ID_OUT'
Line # = 10 Column # = 10 Error Text = PLS-00103: Encountered the symbol "ID_OUT" when expecting one of the following:     := . ( @ % ; The symbol ":=" was substituted for "ID_OUT" to continue.

I think I got it.
CREATE OR REPLACE  PROCEDURE "SCHEMANAME"."SP_XXTESTXX" ( seq_name in
    varchar2)
AS
  id_out varchar(10);
BEGIN
  SP_GET_NEXT_DOC_NUMBER(seq_name,id_out);
  dbms_output.put_line(id_out);
END;This works like I wanted it to do.
