A SYSMAIN function can be performed in either menu or command mode.

This section describes how to use a SYSMAIN menu or a direct command and the options provided when performing a SYSMAIN function.

This section covers the following topics:

• Performing Menu Functions

• Executing Commands

• Description of Functions

• Function Processing and Reporting

• SYSMAIN Online Help

Performing Menu Functions

In menu mode, you perform a SYSMAIN function by entering codes for the object type to be processed and the function to be performed. As an alternative to entering a function code, you can press a corresponding PF key.

To perform a SYSMAIN menu function

• In the SYSMAIN Utility Main Menu, in the Object Code field, enter the one-letter code that corresponds to the objects required (in the example below, A for Programming Objects) and, in the Function Code field, enter the one-letter code that corresponds to the function required (in the example below, C for Copy). As an alternative to entering the function code, you can press the PF key that corresponds to the function (here: PF4); see also the list of PF keys.

  The fields provided in an object-type specific menu depend on the SYSMAIN function performed. Fields that do not apply to a particular function are not displayed on the respective screen.

  The fields are used to specify object selection criteria and processing options. For explanations of the fields, refer to the object-type specific sections of the SYSMAIN utility documentation.

Using PF Keys

You can use PF keys to perform SYSMAIN menu functions. PF keys which are not valid within a menu are not displayed for this menu. The PF keys are summarized in the table below:

Executing Commands

This section provides instructions for executing a SYSMAIN function by using a direct command or issuing a system command from within the SYSMAIN utility.

A direct command is used to perform a SYSMAIN function in either online or batch mode.

In batch mode, a report is automatically provided that shows the status of objects processed. This report can also be displayed in online mode: see Online Report Mode.

This section covers the following topics:

• Issuing Direct Commands

• Using the SYSMAIN Command Line

Issuing Direct Commands

Direct commands consist of a string of keywords that represent parameters. A period (.) indicates the end of a command. If this character is detected anywhere within a command string, all subsequent data is ignored.

The syntax that applies when issuing a direct command is described in the object-type specific sections of the SYSMAIN Utility documentation. The respective keywords and variables are explained in Keywords and Variables in Direct Commands. Examples of direct commands are shown in the object-type specific sections, the SYSMAIN online help and on a Selection screen (see the example screen in Selective Processing).

To issue a direct command online

• At any Natural command prompt, enter the following:

  SYSMAIN

  followed by a command string where each keyword can be delimited by a blank character instead of the delimiter.

  Or:
  In the Command line of any SYSMAIN menu, enter a direct command string where each keyword can be delimited by a blank character instead of the delimiter.

  Or:
  From within a Natural object, invoke the subprogram MAINUSER with the direct command string as a parameter where each keyword can be delimited by a blank character instead of the delimiter.

To issue a direct command in batch

1. Use the command SYSMAIN and specify a command string in either of the following ways:

   1. The command string follows the SYSMAIN command in the same input line; each keyword in the command string can be delimited by a blank character instead of the delimiter.

   2. The command string follows the SYSMAIN command in the next input line; each keyword in the command string must be delimited by the delimiter and not by a blank character.

      If the direct command string is longer than one single line, the characters CF (see also the session parameter CF described in CF - Character for Terminal Commands in the Parameter Reference documentation) must be placed at the end of the line to continue with the direct command in the next line.

2. If you want to execute other Natural commands after the SYSMAIN command(s), you must first terminate SYSMAIN by using the direct command END or QUIT.

Using the SYSMAIN Command Line

In the Command line of any SYSMAIN menu, you can enter one of the following:

• A direct command for processing a SYSMAIN function.

• A special command to the SYSMAIN utility described in Special Commands Issued to SYSMAIN.

• A system command. If the command is not uniquely identifiable as a system command, it must be preceded by two slashes (//). See also Remarks in MAINEX05 - User Exit Routine for Verification of Direct Commands.

Description of Functions

The functions provided in a SYSMAIN menu or as direct commands are described in the following section. For each function provided in a menu, there is a corresponding direct command with the same name. Exception: Help.

For the syntax that applies when using a direct command, refer to the object-type specific sections of the SYSMAIN Utility documentation.

For the special commands that can be issued to the SYSMAIN utility, refer to Special Commands Issued to SYSMAIN.

This section covers the following topics:

• Using the Replace Option

• Listing and Selecting Libraries

Using the Replace Option

If the target environment already contains an object with the same name as the object to be copied, moved or renamed, the specified object is not processed and processing continues with the next object. You can use the replace option to override this default feature and overwrite the object in the target environment.

If a programming object is replaced, it is also deleted from the Natural buffer pool; any existing cross-reference records are also deleted if Predict is installed.

To activate the replace option in command mode

• In the command string, specify the keyword REPLACE.

To activate the replace option in menu mode

1. In a SYSMAIN menu, in the Replace field, enter a Y.

2. Perform a function. If the Sel. List (Selection List) option has been set to N, a window appears where you can choose whether to confirm every replace operation before it is performed: Enter a Y to confirm each replacement, or press ENTER to continue processing without confirmation.

3. If you entered a Y to confirm a replacement, for each object that is to be replaced a window appears where you can enter one of the following characters:

   • Y replaces the object indicated in the window,

   • N does not replace the object indicated in the window (this is the default setting),

   • A period (.) terminates function processing. Alternatively, you can press PF3.

Listing and Selecting Libraries

This option only applies to programming objects, debug environments and error messages.

When using the list function, you can invoke a selection list of libraries that contain the specified object(s). This also applies to the find function if the specified object is contained in several libraries.

To invoke a list of libraries for programming objects

• In a List menu, in the Library field, enter a range of library names (see also Specifying a Range of Names), and, in the Name field, enter an object name or a range of names.

  If you enter an asterisk (*) in the Library field (list function only), a list of all libraries available in the specified system file will be displayed.

  In the example of a Library Selection screen shown below, all libraries with names that start with LIB are selected:

  21:23:03 ***** NATURAL SYSMAIN UTILITY ***** 2005-08-10 User SAG - Library Selection - LIST ALL * IN LIB* WHERE DBID 10 FNR 32 C Library S/C C Library S/C C Library S/C C Library S/C - -------- --- - -------- --- - -------- --- - -------- --- _ LIB1 S/C _ LIB2 S/C _ LIB3 C _ LIB4 S/C _ LIB5 S _ LIB6 S/C _ LIB7 S/C _ LIB8 S/C _ LIB9 S/C _ LIB10 S/C _ LIB11 S/C _ LIB12 S/C _ LIB13 S _ LIB14 S/C _ LIB15 C _ LIB16 S/C _ LIB17 S/C _ LIB18 S/C _ LIB19 S/C _ LIB20 S/C Object Start Value: * Enter options (above), or '?' (Help) or '.' (Exit): _ Enter-PF1---PF2---PF3---PF4---PF5---PF6---PF7---PF8---PF9---PF10--PF11--PF12--- Help Menu Exit Copy Del Find List Move Ren Canc

  The Library column lists all libraries that match the specified range. The S/C column indicates whether a library contains saved (source) objects and/or cataloged objects.

  For a list of line commands available on the Library Selection screen, see Selection Lists for Programming Objects.

When using the find function, the Library Selection screen appears if the specified object is found in several libraries.

The Library Selection screen also appears when you leave a Find Selection or a List Selection screen by pressing PF3 (Quit).

To invoke a list of libraries for debug environments

• In the Debug Environments menu:
  In the Code field, enter an L and, in the Environment Name field, enter the name of a debug environment or a range of names and, in the Source Library field, enter a range of library names (see also Specifying a Range of Names).

  If you enter an asterisk (*) in Environment Name and Source Library, a list of all libraries that contain debug environments in the specified system file will be displayed.

  In the example of a Library Selection screen shown below, all libraries with names that start with L were selected:

  09:55:08 ***** NATURAL SYSMAIN UTILITY ***** 2005-08-10 User SAG - Library Selection - LIST DEBUG * IN LIB* FROM DBID 10 FNR 32 C Library C Library C Library C Library - -------- - -------- - -------- - -------- _ LIB1 _ LIB5 _ LIB9 _ LIB11 _ LIB20 Object Start Value ... * Enter options (above), or '?' (Help) or '.' (Exit): _ Command ===> Enter-PF1---PF2---PF3---PF4---PF5---PF6---PF7---PF8---PF9---PF10--PF11--PF12--- Help Menu Exit Copy Del Find List Move Ren Canc

  The Library column lists all libraries that contain the specified debug environment(s). For a list of line commands available on the Library Selection screen, see Selection Lists for Debug Environments.

To invoke a list of libraries for error messages

• Choose either of the following methods:

  1. In a List menu, in the No. From field, enter an error message number (in the example below, 1) or specify a range of numbers by entering a start number in the No. From field and an end number in the No. To field.

     In the Library field, enter a range of library names (see also Specifying a Range of Names).

     A Library Help window similar to the example below appears:

     14:02:47 ***** NATURAL SYSMAIN UTILITY ***** 2005-08-10 User SAG - List Error Message Texts - +---------------------------+ ! --- Library Help --- ! Code Fun ! - Source - ! ! ! A Lis ! 1 system messages ! E Lis ! 2 LIB1 ! S Lis ! 3 LIB2 ! ? Hel ! 4 LIB3 ! . Exi ! 5 LIB4 ! ! 6 LIB5 ! Code ...... A ! 7 LIB6 ! ! 8 LIB7 ! Error No. From .. 1___ ! ! Source Library ...

     From the window, select a library by entering the number that corresponds to the required library as shown in the example above where 8 was entered to select LIB7. If you have specified the correct FNAT system file, you can also select system error messages. If required, press enter to scroll to the end of the list.

  2. In a Find menu, in the Number field enter an error message number, and, in the Library field, enter a range of library names (see also Specifying a Range of Names).

     A Find Selection screen similar to the example below appears for the specified range of libraries (here: LIB*):

     19:09:34 ***** NATURAL SYSMAIN UTILITY ***** 2005-08-10 User SAG - Find Selection - FIND ERR 1 TYPE A FROM LIB* LANG * WHERE DBID 10 FNR 32 C Library Error Message Text(s) for Error number: 1 Type - -------- --------------------------------------------------------- ---- _ LIB1 Short message of Error 1: wrong input value.

S/E _ LIB8 Short message of Error 1: input missing. S/E _ LIB9 Short message of Error 1: undefined keyword. S/E _ LIB10 Short message of Error 1: invalid command. S Enter options (above), or '?' (Help) or '.' (Exit): __ Enter-PF1---PF2---PF3---PF4---PF5---PF6---PF7---PF8---PF9---PF10--PF11--PF12--- Help Menu Exit Copy Del List Move Ren Canc

     The Library column lists all libraries that contain the specified error message(s) (here: 1). The Type column indicates whether the short (S) and/or the extended (E) error message is available for the specified message.

     For a list of line commands available on the Find Selection screen, see Selection Lists for Error Messages.

Function Processing and Reporting

There are two types of processing that can be used when performing a SYSMAIN function: selective processing and automated processing.

This section describes the two types of function processing and how to obtain a status report about function processing:

• Automated Processing

• Selective Processing

• Using a Selection List

• Online Report Mode

Automated Processing

Automated processing is the default type of processing when operating online in command mode. In batch mode, automated processing is the standard type of processing.

Automated processing is an online or batch facility which processes objects without displaying an intervening selection list. This requires little or no terminal I/O after a function has been selected.

Using automated processing online, the status of individual objects is not displayed, but an appropriate message is displayed upon completion of processing. If any of the following Natural system error messages is displayed, some or all of the specified objects were not processed:

4867:Nothing found for this request.
4810:All data rejected by these selection criteria.
4893:Normal completion, but some data were rejected.

The extended (long) message text of error NAT4810 lists reasons why an object may not have been processed. Reasons for an object not to be processed are also discussed in the section Processing Status and Error Notification.

Batch mode or selective processing should be used if it is necessary to see the status of each object after it is processed.

If required, when operating online, you can obtain a batch report with the processing status of all objects as described in Online Report Mode.

Selective Processing

Selective processing is the default type of processing when operating in menu mode.

Selective processing is an online facility which displays a selection list of all objects that meet the specified selection criteria. A selection list provides the following options:

• Select single or multiple objects for further processing.

• Perform an additional function on an object (for example, displaying the source code) before processing it (see: Using a Selection List).

• Obtain individual messages on the processing status of each object (for example, Moved or Copied).

• View the direct command that corresponds to the input values entered in the SYSMAIN menu (see the example of a selection screen below). This may be of help when using direct commands instead of menu functions.

Using a Selection List

This section provides instructions for invoking a selection list to further process single or multiple objects. In addition, this section describes how to shorten a selection when using the list or find function. This option is useful with large libraries in order to restrict the number of objects being displayed.

To use a selection list online

1. In menu mode: In a SYSMAIN menu, in the Sel. List field, enter a Y (this is the default setting) to activate selective processing. Input of an N deactivates selective processing.

   Or:
   In command mode: Include the keyword HELP in the with-clause of the direct command or enter a question mark (?) immediately after the object name; see also the syntax diagrams in the object-type specific sections of the SYSMAIN Utility documentation.

   When selective processing has been activated, a Selection screen similar to the example below appears:

   11:05:22 ***** NATURAL SYSMAIN UTILITY ***** 2005-08-10 User SAG - Copy Selection - COPY ALL * WITH XREF N FROM OLDLIB WHERE DBID 10 FNR 50 TO NEWLIB WHERE DBID 10 FNR 60 C Name Type S/C Message C Name Type S/C Message - -------- ------ --- ------------ - -------- ------ --- ------------ _ AA Copycd S/C _ G0000001 Global S _ G0000002 Global S/C _ G0000003 Global S/C _ L0000001 Local S/C _ L0000002 Local S/C _ L0000003 Local S _ M0000001 Map S _ M0000002 Map S/C _ M0000003 Map S/C _ P0000001 Progrm S _ P0000002 Progrm C _ P0000003 Progrm S/C _ P0000004 Progrm S/C _ P0000005 Progrm S _ P0000006 Progrm S/C _ P0000007 Progrm S/C _ S0000001 Subpgm S/C _ S0000002 Subpgm S/C _ S0000003 Subpgm S _ T0000001 Text S _ T0000002 Text Listed Library: OLDLIB Enter options (above), or '?' (Help) or '.' (Exit) _ Enter-PF1---PF2---PF3---PF4---PF5---PF6---PF7---PF8---PF9---PF10--PF11--PF12--- Help Menu Exit Copy Del Find List Move Ren Canc

   The list contains the names and the types of the specified objects and indicates whether saved objects (S) and/or cataloged (C) objects exist.

   The lines above the selection list (highlighted in the example above) displays the SYSMAIN direct command that corresponds to the input values you entered in the menu fields.

   This command corresponds to the command syntax that applies when you work in command mode, although some keywords are optional, as shown in the syntax diagrams in the object-type specific sections of the SYSMAIN documentation.

2. Select one or more objects for further processing: In the C (command) column next to the object(s) desired, enter one of the line commands described in the object-type specific sections of the SYSMAIN Utility documentation.

3. Press ENTER to perform one or more line commands.

   Line commands are executed in alphabetical order of the specified object names whereby commands that perform a SYSMAIN maintenance function (for example, delete) are always executed last.

   If no SYSMAIN maintenance function (for example, displaying source code) was performed on any object, you can again enter a line command for any object(s). However, once a SYSMAIN maintenance function has been performed on any object(s), the fields of the C column are no longer available for input.

   If a line command has been executed, the status of the object(s) processed is displayed in the Message column as shown in the example below:

   11:05:22 ***** NATURAL SYSMAIN UTILITY ***** 2005-08-10 User SAG - Copy Selection - COPY ALL * WITH XREF N FROM OLDLIB WHERE DBID 10 FNR 50 TO NEWLIB WHERE DBID 10 FNR 60 C Name Type S/C Message C Name Type S/C Message - -------- ------ --- ------------ - -------- ------ --- ------------ _ AA Copycd S/C Copied _ G0000001 Global S Copied _ G0000002 Global S/C Copied _ G0000003 Global S/C Copied _ L0000001 Local S/C Copied _ L0000002 Local S/C Copied _ L0000003 Local S Replaced _ M0000001 Map S Replaced _ M0000002 Map S/C Replaced _ M0000003 Map S/C Replaced _ P0000001 Progrm S _ P0000002 Progrm C _ P0000003 Progrm S/C _ P0000004 Progrm S/C _ P0000005 Progrm S _ P0000006 Progrm S/C _ P0000007 Progrm S/C _ S0000001 Subpgm S/C _ S0000002 Subpgm S/C _ S0000003 Subpgm S _ T0000001 Text S _ T0000002 Text Listed Library: OLDLIB Enter options (above), or '?' (Help) or '.' (Exit) _ Enter-PF1---PF2---PF3---PF4---PF5---PF6---PF7---PF8---PF9---PF10--PF11--PF12--- Help Menu Exit Copy Del Find List Move Ren Canc

   For a list of possible status messages, see Status Messages in the section Processing Status and Error Notification.

To shorten a selection list

• On a List Selection or Find Selection screen, in the Reposition to field, enter the name of an object or specify a range of names (see Specifying a Range of Names) and press ENTER.

  If you have specified a name, the list now starts from the specified name. If you have specified a range of names, the list now displays only objects within that range.

  The Reposition to option is only valid in online mode. It is not a selection criterion for the list function.

Online Report Mode

Online report mode can be used to obtain a SYSMAIN batch report online instead of a selection list. An online batch report lists all objects that were affected by a SYSMAIN function and indicates the action performed on each of these objects.

To use a batch report online

1. In a SYSMAIN menu, in the Sel. List (Selection List) field, enter an N to activate automated processing.

2. In the Command line, enter one of the following direct commands:

   BATCH

   or

   BAT

   A message appears confirming that batch mode has been activated.

3. If required, you can obtain a hardcopy of the report by entering the following terminal command:

   %H

   (See also %H - Hardcopy Output in the Terminal Commands documentation.)

4. Execute a SYSMAIN function. SYSMAIN now processes the function as if in batch mode. Hence, only the result of each action is present in a report-type format as shown in the example below:

   10:50:30 ***** NATURAL SYSMAIN UTILITY ***** 2005-08-10 User SAG - Copy Function - COPY ALL * WITH XREF N FROM TESTLIB1 WHERE DBID 10 FNR 30 TO TESTLIB2 WHERE DBID 10 FNR 40 Saved Progrm TEST1 has now been Copied Saved Progrm TEST2 has now been Copied Saved Progrm TEST3 has now been Copied Stowed Progrm TEST4 has now been Copied Stowed Progrm TEST5 has now been Copied Stowed Progrm TEST6 has now been Copied Stowed Progrm TEST7 has now been Copied Saved Record TEST8 has now been Copied Saved Text TEST9 has now been Copied Cataloged Progrm TEST10 has now been Copied Saved Progrm TEST11 has now been Copied Stowed Progrm TEST12 has now been Copied MORE Stowed Progrm TEST13 has now been Copied Cataloged Progrm TEST14 has now been Copied Stowed Progrm TEST15 has now been Copied

5. If required, you can interrupt function processing by entering a system command or terminal command at a MORE prompt. Otherwise, press ENTER until you have reached the end of the list and return to the SYSMAIN menu where a message confirms successful execution of the function.

SYSMAIN Online Help

The SYSMAIN online help facility provides information on all functions provided by SYSMAIN including detailed explanations of the direct command syntax and examples of direct commands.

In addition to the help facility, SYSMAIN provides individual information on any input field available on any SYSMAIN screen.

To invoke SYSMAIN help topics

1. In the SYSMAIN Utility Main Menu, position the cursor in the Object Code or the Function Code field and press PF1 (Help) or enter a question mark (?).

   The Help Menu of the SYSMAIN utility appears similar to the example below with a list of help topics provided:

   15:54:28 ***** NATURAL SYSMAIN UTILITY ***** 2005-08-10 User SAG - Help Menu - Help Name SHT-0001 Code Topic A SYSMAIN General Overview C Command Mode E Environment Definition F Functions / Commands S Security Environment . Exit Code ... _ Select a function code. Enter-PF1---PF2---PF3---PF4---PF5---PF6---PF7---PF8---PF9---PF10--PF11--PF12--- Menu Exit Canc

2. In the Code field, enter the one-letter code that corresponds to the help topic desired.

3. Press ENTER.

   A result screen appears with information on the help topic selected, or another menu is invoked with further help topics that help narrow down your search.

To invoke help on an input field

• Position the cursor in the field in question and press PF1 (Help) or enter a question mark (?) and press ENTER.

  A window appears with field-specific instructions and, where applicable, a list of valid input values.
