SYSCP Utility - Code Page Administration

The SYSCP utility is used to obtain information on code pages and ICU (International Components for Unicode) data libraries available in the current Natural mainframe environment. In addition, you can use the SYSCP utility to change the code page assignment of programming objects, DDMs, profiles and error messages. You can also add, remove or convert code pages.

The SYSCP utility also offers you help to avoid problems that can occur when a code page is not defined or enabled in Natural or when objects are converted to an incorrect code page or Unicode format.

For detailed information on how Natural supports Unicode and code pages and Unicode-specific items, see the descriptions and presentations in the SYSEXV Utility and Related Topics below.

Note:
The use of the SYSCP utility can be controlled by Natural Security. For detailed information, see the section SYSCP - Code Page Administration - Utility Profiles in the Natural Security documentation.

The SYSCP Utility - Code Page Administration documentation covers the following topics:

Code Page Maintenance

The Code Page Maintenance menu provides functions that can be applied to programming objects (N), DDMs (D), profiles (P), user error messages (E) and system error messages (S). For an object you can list (L), assign (A) or remove (R) code page information. You can also convert (C) a code page or check its conversion for assigned (K) or unassigned (C) objects.

All code page maintenance functions reference the standard IANA name (see also Cmd in All Code Pages); you cannot use a code page name other than IANA when you execute a code page maintenance function.

The results of a code page maintenance function are output on a report screen, which is described in Function Result Report.

When you invoke Code Page Maintenance, a maintenance menu similar to the example below appears:

Check Conversion of Unassigned Objects

This function is used to check whether an unassigned object can be converted to a code page.

An unassigned object is an object without code page information, which was originally saved under a Natural version where code page information was not yet supported. Since no code page information is provided, you need to decide which code page to specify for the object to be checked for conversion. This depends on the character set used in the object.

For example, if you apply the function Check Conversion of Unassigned Objects to Profiles, a screen similar to the example below appears:

  • PF8 (or ENTER) scrolls down one page in the list.

  • PF7 scrolls up one page in the list.

  • PF5 sorts the list in ascending order by code page name. Depending on the size of the list, you may have to increase the size of the sort buffer by using the SORT profile parameter as described in SORT - Control of Sort Program in the Parameter Reference documentation.

The columns contained in the All Code Pages screen are explained in the following table:

Column Explanation
Cmd
Input field for one of the following line commands to be executed for the selected code page:
   
N Display all names used for the code page:

The IANA (Internet Assigned Numbers Authority) name is the standard and unambiguous name of the code page. The IANA name is used by Natural as the default code page name (see the CP profile parameter described in the Parameter Reference documentation) for conversions to and from Unicode. The IANA name is returned by the *CODEPAGE system variable (see the System Variables documentation).

CCSID (Coded Character Set Identifier) denotes the character set as identified by IBM.

Alias names: one or more alternate names for the code page.

   
C Display all code points of the selected code page: see Code Point List below.
   
T Invoke a window to test code point conversion to and from Unicode: see Test Conversion.
Stat
All code pages to be used during a Natural session must be predefined and enabled in the NATCONFG module.

This column shows the NATCONFG status of the code page:

   
E Code page is defined in the NATCONFG module and is enabled.
   
D Code page is defined in NATCONFG but is disabled.
   
N Code page is not defined in NATCONFG.
   
For detailed information on the NATCONFG module, refer to Natural Configuration Tables in the Operations documentation.
Name The internal ICU name.
Units The code units (minimum and maximum numbers of bytes) assigned to the code points.

The list contains the following information:

  • The byte sequence of the code page code points (CP).

  • The byte sequence of the corresponding Unicode code points (U).

  • The Unicode character. If the character cannot be interpreted by the current terminal emulation, the substitution character (as defined in the code page; here: ?) is displayed instead.

  • The normative name of the Unicode character.

The PF keys provided for each code point list are explained in the following table:

PF Key Function
PF4 Not applicable to a code page with a 1-byte unit as the maximum.

Opens the Leading Bytes of Code Point window (see the relevant section) in which you can enter the byte range you want to view.

Press PF3 or ENTER to confirm your current input of leading bytes and to close the window.

Press PF12 to cancel your current input and to close the window.

PF5 Invokes the Unicode Properties screen (see the relevant section) for the list item where the cursor is placed.
PF6 Resets the first (non-leading) byte of the byte range to the hexadecimal value 0x00.
PF7 Scrolls up one page in the selected byte range (see also Specifying Leading Bytes).

In a UTF-16 or UTF-32 code page, you can scroll through all byte ranges.

PF8
(or ENTER)

Scrolls down one page in the selected byte range (see also Specifying Leading Bytes).

In a UTF-16 or UTF-32 code page, you can scroll through all byte ranges.

PF10 Moves to the leftmost screen position.
PF11 Moves to the right of the screen.

Specifying Leading Bytes

This function does not apply to a code page with a 1-byte unit as the maximum.

You can use the Leading Byte of Code Point window to view the byte range (hexadecimal values 0x00 to 0xFF) of a particular leading byte for a code point.

In the following example of a UTF-8 code page, the hexadecimal values 0x22 and 0x32 have been entered as the leading bytes:

+--------- Leading Bytes of Code Point ---------+
!                                               !
!    Maximum number of bytes .. 3               !
!                                               !
!                                               !
!    Enter leading bytes ...... 00 22 32 00     !
!                                               !
!                                               !
!                                               !
+-----------------------------------------------+

After pressing PF3 (or ENTER) the code point list then displays the bytes from hexadecimal 0x00223200 to 0x002232FF.

Note:
For byte-swapped code pages such as UTF-16LE or UTF-32LE, the bytes are read and displayed in a reversed byte order.

Test Conversion

You can test code-point conversion from a selected code page to the default code page (value of *CODEPAGE) defined with the CP profile parameter:

  • from an alphanumeric character string to Unicode code points and vice versa, or

  • from hexadecimal values to Unicode code points and vice versa.

The example below shows the conversion window of a code page (here: ibm-1140_P100-1997) which contains the following information:

  • the number of byte units (minimum and maximum numbers of bytes) assigned to the code points,

  • an alphanumeric character string and its equivalent hexadecimal values and

  • the corresponding Unicode code points.
