|  | //prototype// |
|  | **END** |

{{blk2blue.jpg|blk2blue.jpg}}

| **MODULE** | Names a MEMBER module or external library file. |
| //sourcefile// | A string constant which contains the filename of the Clarion language source code file containing the definitions of the PROCEDUREs. If the //sourcefile// is an external library, this string may contain any unique identifier. |
| //prototype// | The prototype of a PROCEDURE whose definition is contained in the //sourcefile//. |

A **MODULE** structure names a Clarion language MEMBER module or an external library file and contains the //prototypes// for the PROCEDUREs contained in the //sourcefile//. A MODULE structure can only be declared within a MAP structure and is valid for use in any MAP structure, whether that MAP is in a PROGRAM module or MEMBER module.

**Example:**

**!The "sample.clw" file contains:**

** PROGRAM               !Sample program in sample.clw**

** MAP                   !Begin map declaration**

** ****MODULE('Loadit')****     ! source module loadit.clw**

**LoadIt PROCEDURE       ! LoadIt procedure**

** ****END****                  ! end module**

** ****MODULE('Compute')****    ! source module compute.clw**

**ComputeIt PROCEDURE    ! compute it procedure**

** ****END****                  ! end module**

** END                   !End map**

**!The "loadit.clw" file contains:**

** MEMBER('Sample')      !Declare MEMBER module**

** MAP                   !Begin local map declaration**

** ****MODULE('Process')****    ! source module process.cla**

**ProcessIt PROCEDURE    !  process it procedure**

** ****END****                  ! end module**

** END                   !End map**
