The Software AG Editor is an optional Natural component that is required by several Natural utilities (for example, SYSRPC and SYSBPM), Natural add-on products (for example, Natural ISPF) and other Software AG products (for example, Predict).

This document describes the steps for installing the Software AG Editor on z/VSE.

Installation Procedure

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

The System Maintenance Aid (SMA) parameter SAG-EDITOR is set to Y (Yes) by default to allow installation of the Software AG Editor.

• Step 1: Adapt the Editor Buffer Pool Parameter Macro NTEDBP

• Step 2: Allocate the Editor Work File

• Step 3: Format the Editor Work File

• Step 4: Modify the Startup JCL and Subsystem Definitions

• Step 5: Build the Natural Parameter Module

• Step 6: Define the Global Editor Buffer Pool

• Step 7: Link the Software AG Editor to the Nucleus

Step 1: Adapt the Editor Buffer Pool Parameter Macro NTEDBP

1. Modify the editor buffer pool settings supplied with the NTEDBP macro in the Natural parameter module to meet your requirements. For a description of this macro, see the corresponding dynamic profile parameter EDBP.

2. Assemble the Natural parameter module and link it to the Software AG Editor work file formatting utility (NATEDFMV) contained in the Natural load library. The Software AG Editor work file formatting utility is described in Editor Work File in the Operations documentation.

   The editor buffer pool parameters contained in the Natural parameter module are stored in the editor buffer pool work file control record during formatting (see Step 3: Format the Editor Work File).

For the Initial Installation:

You can leave the defaults. In this case, it is not necessary to assemble and link the Natural parameter module.

Step 2: Allocate the Editor Work File

(Job I008, Steps 1900, 1901, 1903, 1905)

Under Com-plete, this step is only required if you want to use a global editor buffer pool.

A VSAM RRDS is used as the editor work file. To best exploit the VSAM data set space, the record length should be defined 8 bytes less than the control interval length; see also Editor Work File in the Operations documentation.

• Depending on your TP monitor environment, execute the following steps to allocate the data set:

  Step 1900 ALLOCATE EDITOR WORK FILE BATCH 
       1901 ALLOCATE EDITOR WORK FILE CICS  
       1903 ALLOCATE EDITOR WORK FILE TSO   
       1905 ALLOCATE EDITOR WORK FILE GLOBAL

Step 3: Format the Editor Work File

(Job I081, Steps 1900, 1901, 1903, 1905)

Under Com-plete, this step is only required if you want to use a global editor buffer pool.

1. Use the Software AG Editor work file formatting utility (NATEDFMV) to format and load the control record in the editor work file.

2. Depending on your TP monitor environment, execute the following steps to format the data set:

   Step 1900 FORMAT EDITOR WORK FILE BATCH
        1901 FORMAT EDITOR WORK FILE CICS
        1903 FORMAT EDITOR WORK FILE TSO
        1905 FORMAT EDITOR WORK FILE GLOBAL

Step 4: Modify the Startup JCL and Subsystem Definitions

You can specify the data set to be used for the editor work file by either adding the appropriate DLBL statement or using the keyword subparameter DDNAME of the parameter macro NTEDBP (see EDBP - Software AG Editor Buffer Pool Definitions in the Parameter Reference documentation).

The data set name specified with DDNAME must correspond to the data set definition in your JCL.

• In Batch Mode:

  Add a DLBL statement for the editor work file:

  // DLBL CMEDIT,'data-set-name',,VSAM,CAT=catalog-name

  where:
  data-set-name is the name of the data set to be used for the work file,
  catalog-name is the name of the VSAM catalog that holds the information about the data set.

  Instead of using an actual VSAM file, you can also define a dummy editor work file by using JCL or standard labels (see the Example below). Such a label definition enables you to use the editor and the editor buffer pool. However, any write access to the editor work file will lead to an error, and you cannot use the recovery feature.

  Example:

  // DLBL CMEDIT,'SAG.EDITOR.WORK.FILE',,VSAM,CAT=catalog-name
  // EXTENT SYSnnn
  // ASSGN SYSnnn,IN

  where nnn is a valid SYS number.

• Under Com-plete:

  • If you want to use a global editor buffer pool, add a DLBL statement for the editor work file:

    // DLBL dlbl-name,'data-set-name',,VSAM,CAT=catalog-name

    where:
    dlbl-name is the name of the global editor buffer pool,
    data-set-name is the name of the data set to be used for the work file,
    catalog-name is the name of the VSAM catalog that holds the information about the data set.

    In addition, the DLBL name has to be defined to Com-plete by using the UUTIL utility function FM (described in the relevant section of the Com-plete documentation).

  • If you want to use a local editor buffer pool, define an SD file as the editor work file. The name of the SD file is indicated in the keyword subparameter DDNAME of the NTEDBP macro.

    The number of work file records is set with the keyword subparameter RECNUM and the work file record length is set with the keyword subparameter LRECL of the NTEDBP macro.

    For a local editor buffer pool, add the definitions of the editor buffer pool to the SERVER parameter of your startup parameters as indicated in Define the Natural Com-plete/SMARTS Interface Server in the section Installing Natural Com-plete/SMARTS Interface.

    For explanations of the keyword subparameters and macros mentioned above, see EDBP - Software AG Editor Buffer Pool Definitions in the Parameter Reference documentation.

• Under CICS:

  Add an entry in the CICS File Control Table (Job I005).

Step 5: Build the Natural Parameter Module

(Job I080)

1. Add the following parameter to your Natural parameter module to specify the size of the editor area:

   SSIZE=nn

   where nn must be set to at least 54 (the default is 64).

2. The Software AG Editor requires either a local or a global editor buffer pool (see also Natural Buffer Pools in the Operations documentation).

   • If you want to use a local editor buffer pool, specify the NTBPI macro as follows:

     NTBPI TYPE=EDIT

     The size of the region must be large enough to allocate the local buffer pool.

     For more information on NTBPI, see NTBPI Macro Syntax in the Parameter Reference documentation.

   • If you want to use a global editor buffer pool, proceed as follows:

     Specify the NTBPI macro as follows:

     NTBPI TYPE=EDIT,NAME=gbp-name

     where gbp-name is the name of the global editor buffer pool to be used.

     Supply the following parameter with the NTPRM macro (described in the Operations documentation):

     SUBSID=subsystem-name

     where subsystem-name is the name of the Natural subsystem specified when creating the global buffer pool.

     For detailed information on SUBSID, see SUBSID - Subsystem ID under z/OS and z/VSE in the Parameter Reference documentation.

3. Assemble and link the Natural parameter module.

Step 6: Define the Global Editor Buffer Pool

The global editor buffer pool can be shared by several regions. It is defined and started using the same procedure as for Natural global buffer pools; see Natural Global Buffer Pool under z/VSE in the Operations documentation. The parameter setting TYPE=EDIT identifies the buffer pool as an editor buffer pool.

All users of the same global editor buffer pool must share the same editor work file; otherwise, an error occurs.

Step 7: Link the Software AG Editor to the Nucleus

(Job I080)

• Link the following Software AG Editor module to either the environment-independent nucleus or the environment-dependent nucleus by using the corresponding INCLUDE statement:

   INCLUDE NATEDT

• Instead of linking the Software AG Editor module to the nucleus, you can dynamically load it during initialization of a Natural session. In this case, the NATEDT editor module must be linked as EDITOR object module and the Natural session must be started with the profile parameter setting RCA=EDITOR (see also RCA - Resolve Addresses of Statically Linked Modules described in the Parameter Reference documentation).

Installation Verification

You can verify the successful installation of the Software AG Editor by performing the following:

• Invoke Natural and enter the following system command:

  SYSEDT

  The SYSEDT Utility Main Menu appears, which can be used to display all buffer pool parameters and usage statistics; see SYSEDT Utility - Editor Buffer Pool Administration in the Utilities documentation.

You can only test the full operation of the Software AG Editor if another Software AG product (for example, Natural ISPF or Predict) that uses Software AG Editor functionality is installed.
