Compiling CL source program
A CL source program must be compiled before it can be run.
To create a CL program in one step, you can use the Create CL Program (CRTCLPGM) command or the Create Bound Control Language Program (CRTBNDCL) command, which create a bound program with one module.
You can also create a CL module with the Create Control Language Module (CRTCLMOD) command. The module must then be bound into a program or service program using the Create Program (CRTPGM) or Create Service Program (CRTSRVPGM) command.
You can use the Include CL Source (INCLUDE) command to embed another source file during compilation.
The following example creates the module ORD040C and places it in library DSTPRODLB:
CRTCLMOD MODULE(DSTPRODLB/ORD040C) SRCFILE(QCLSRC)
TEXT('Order dept general menu program')
The source commands for ORD040C are in the source file QCLSRC, and the source member name is ORD040C. By default, a compiler listing is created.
On the Create CL Program (CRTCLPGM) command or the Create Bound Control Language Program (CRTBNDCL) command, you can specify listing options and whether the program should operate under the program owner's user profile.
A program can run using either the owner's user profile or the user's user profile.
- Setting create options in the CL source program
With the Declare Processing Options (DCLPRCOPT) command, you can set many of the same create option parameters that are on the CL compiler commands. The CL compiler commands include Create CL Program (CRTCLPGM), Create CL Module (CRTCLMOD), and Create Bound CL Program (CRTBNDCL). - Embedding CL commands from another source member
You can use the Include CL Source (INCLUDE) command to split your CL source code, so that the CL source code can be compiled across multiple source file members. - Logging CL program or procedure commands
You can specify that most CL commands that are run in a CL program or procedure be written (logged) to the job log. 
Retrieving CL source code
Depending on the CL compiler options used, you can retrieve the CL source code from a CL program or CL module object.- CL module compiler listings
When you create a CL module, you can create various types of listings using the OPTION and OUTPUT parameters on the Create Control Language Module (CRTCLMOD) command. - Common compilation errors
The types of errors that are detected at compile time include syntax errors, references to variables and labels not defined, and missing statements. - Obtaining a CL dump
You can obtain a CL program or CL procedure dump while the CL program or CL procedure is running. - Displaying module attributes
To display the attributes of any module object, including a CL module, use the Display Module (DSPMOD) command. - Displaying program attributes
To display the attributes of any program object, including a CL program, use the Display Program (DSPPGM) command. - Return code summary
A return code can be returned using the Return code (RTNCDE) parameter on the Retrieve Job Attributes (RTVJOBA) command .
