Installation Procedure

Be sure to read Installation Process and Major Natural Features before you start the installation procedure.

Step 1: Build the Natural Parameter Module

(Jobs I060 and I080)

  1. Activate the Natural Optimizer Compiler by adding the following macro to your Natural parameter module: 

    NTOPT 'INDX,OVFLW,ZD=OFF'

    See also Macro NTOPT in the Natural Optimizer Compiler documentation.

  2. Assemble and link the Natural parameter module.

Step 2: Relink the Nucleus or Dynamically Load Modules

You can either statically link the Natural Optimizer Compiler modules to the nucleus or dynamically load them when initializing a Natural session.

Relink the Nucleus:

(Jobs I060, I080)

Adapt the link steps for Natural:

  1. Add the following INCLUDE statement to the link of the nucleus to include the Natural Optimizer Compiler modules: 

     INCLUDE NOCNUC

  2. Relink your nucleus as described in Link the Nucleus in Installing Natural.

Dynamically Load Phases

  1. Add the library containing the phases statement:

    // LIBDEF PHASE,SEARCH=(,,,,,SAGLIB.NOCvrs,...),TEMP

  2. At the start of a Natural session, set the Natural profile parameter RCA as follows: 

    RCA=NOCGW,RCALIAS(NOCGW,NOCNUC)

    RCA is described in the Parameter Reference documentation.

Installation Verification

You can verify the successful installation of the Natural Optimizer Compiler by performing the following steps:

  1. Recatalog an existing program or write a new program and then catalog it.

  2. Check the directory information for the program you have just cataloged, by using the following LIST system command: 

    LIST DIR object-name

    The directory information for the specified object will be displayed, showing the size of the machine code at the bottom of the screen.
