REG_CREATE_KEY, DISPLAY_REG_CREATE_KEY

Creates a specified registry key by providing access to the Windows registry routine RegCreateKey. If the key already exists, this function opens it (same functionality as REG_OPEN_KEY). If the key does not exist, it is created and then opened.

Use DISPLAY_REG_CREATE_KEY when you want the action to be performed on the display host's registry (the local host when the application is run with a standard runtime; the thin client when the application is run with the thin client). Use REG_CREATE_KEY when you want the action to be performed on the server host's registry (the local host when the application is run with a standard runtime, and the application host when the application is run with the thin client).

Usage

CALL "REG_CREATE_KEY" 
    USING OPEN-KEY-HANDLE, SUBKEY-TO-BE-CREATED, 
        SUBKEY-HANDLE 
    GIVING STATUS-CODE

Parameters

OPEN-KEY-HANDLE Usage unsigned-long	Handle of a currently open key or one of the following predefined handles of keys that are always open (defined in acugui.def): HKEY_CLASSES_ROOT HKEY_CURRENT_USER HKEY_LOCAL_MACHINE HKEY_USERS The key created or opened by REG_CREATE_KEY is a subkey of the key identified by OPEN-KEY-HANDLE.
SUBKEY-TO-BE-CREATED PIC X(n)	Name of the subkey to create or open.
SUBKEY-HANDLE Usage unsigned-long	Data item to receive the handle of the newly created or opened key.
STATUS-CODE Numeric data item.	Receives the return status of the call to Microsoft's `RegCreateKey` function. A return status of zero indicates success; non-zero indicates that an error occurred.

Comments

REG_CREATE_KEY may be used to create several keys at once.

For example, by setting SUBKEY-TO-BE-CREATED to

     "key1\key2\key3"

you could create three keys, where key3 is a subkey of key2, key2 is a subkey of key1, and key1 is a subkey of the key specified by OPEN-KEY-HANDLE. The lowest-level key (key3 in this example) is the one that is opened and has its handle returned in SUBKEY-HANDLE.
