The SYSCP utility is used to obtain information on code pages and ICU (International Components for Unicode) data files available in the current Natural mainframe environment. In addition, you can use the SYSCP utility to change the code page assignment of a source object or convert code pages for a source object.
This helps avoid problems that can occur when a code page is not defined or enabled in Natural or when source 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 application 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:

The functions are used to list the code page information of source objects contained in a Natural library, change code page assignments of source objects and convert code pages for source 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 , a maintenance menu similar to the example below appears:

This function is used to check whether an unassigned source object can be converted to a code page.
An unassigned source 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 source object to be checked for conversion. This depends on the character set used in the source.
If you invoke the function, a screen similar to the example below appears:
14:56:51 ***** NATURAL SYSCP UTILITY ***** 2006-10-19

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 |
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. |
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.
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:
