How Can Control Transactions For Creating Stored Procedure ?

I create StringBuilder type for
concating string to create a lot of stored procedure at once
 
However When I use this command
 
BEGIN TRANSACTION
BEGIN TRY
--////////////////////// SQL COMMAND /////////////////////////
           -------------------- This any command

--///////////////////////////////////////////////////////////
    --COMMIT TRAN
END TRY

BEGIN CATCH
    IF @@TRANCOUNT > 0
        ROLLBACK TRANSACTION;
END CATCH

IF @@TRANCOUNT > 0
    COMMIT TRANSACTION;
 
 
on any command 
If I use
Create a lot of Tables
such as

 
BEGIN TRANSACTION

BEGIN TRY

--////////////////////// SQL COMMAND /////////////////////////
CREATE TABLE [dbo].[Table1](
     Column1 Int ,
     Column2 varchar(50) NULL
 ) ON [PRIMARY]

CREATE TABLE [dbo].[Table2](

     Column1 Int ,

     Column2 varchar(50) NULL

 ) ON [PRIMARY]


CREATE TABLE [dbo].[Table3](


     Column1 Int ,


     Column2 varchar(50) NULL


 ) ON [PRIMARY]


--///////////////////////////////////////////////////////////

    --COMMIT TRAN

END TRY



BEGIN CATCH

    IF @@TRANCOUNT > 0

        ROLLBACK TRANSACTION;

END CATCH



IF @@TRANCOUNT > 0

    COMMIT TRANSACTION;
 
 
It correctly works.
 
But if I need create a lot of Stored procedure
 
as the following code :
 


 
BEGIN TRANSACTION

BEGIN TRY

--////////////////////// SQL COMMAND /////////////////////////

CREATE PROCEDURE [dbo].[DeleteItem1]

    @ProcId        Int,

    @RowVersion        Int

AS

BEGIN

    DELETE FROM [dbo].[ItemProcurement]

    WHERE

        [ProcId]    =    @ProcId    AND

        [RowVersion]    =    @RowVersion   

END
 
CREATE PROCEDURE [dbo].[DeleteItem2]


    @ProcId        Int


AS


BEGIN


    DELETE FROM [dbo].[ItemProcurement]


    WHERE


        [ProcId]    =    @ProcId 


END



CREATE PROCEDURE [dbo].[DeleteItem3]



    @ProcId        Int



AS



BEGIN



    DELETE FROM [dbo].[ItemProcurement]



    WHERE



        [ProcId]    =    @ProcId 



END



--///////////////////////////////////////////////////////////

    --COMMIT TRAN

END TRY



BEGIN CATCH

    IF @@TRANCOUNT > 0

        ROLLBACK TRANSACTION;

END CATCH



IF @@TRANCOUNT > 0

    COMMIT TRANSACTION;

It occurs Error ?????
