how to save created objects in GTA SAMP?

Question

I'm writing code in Pawn language in visual studio. I can create an object, but how can I save it so that the player can later see a list of created objects?

I need to add a command for example /list - where a dialog box like DIALOG_STYLE_TABLIST_HEADERS will open, and information about the created objects will be displayed as: "Name" "Object ID" "Who created the object (Nickname)"

I have this code:

#include <a_samp>

#define DIALOG_SOE          1050
#define DIALOG_CREATE       DIALOG_SOE + 1
#define DIALOG_SELECT       DIALOG_SOE + 2
#define DIALOG_TUTORIAL     DIALOG_SOE + 3
#define DIALOG_SAVE_1       DIALOG_SOE + 4
#define DIALOG_SAVE_2       DIALOG_SOE + 5

enum SavedEnums {
    Float:foX,
    Float:foY,
    Float:foZ,
    Float:roX,
    Float:roY,
    Float:roZ
};

new O[SavedEnums];

public OnPlayerCommandText(playerid, cmdtext[])
{
    if(strcmp("/soe", cmdtext, true, 10) == 0)
    {
        if(0 == IsPlayerAdmin(playerid))
            return 1;

        ShowPlayerDialog(playerid, DIALOG_SOE, DIALOG_STYLE_LIST, "Object Editor", \
        "Instructions\nCreate Object\nEdit Map","Select","Cancel");
        return 1;
    }
    return 0;
}

public OnDialogResponse(playerid, dialogid, response, listitem, inputtext[])
{
    switch(dialogid)
    {
        case DIALOG_SOE:
        {
            if(response)
            {
                if(listitem == 0) ShowPlayerDialog(playerid, DIALOG_TUTORIAL, DIALOG_STYLE_MSGBOX, \
                "Instructions","{FFFFFF}Hotkeys:\n\n{008080}Escape {FFFFFF}- to exit the editor or select an object\n{008080}Shift {FFFFFF}- to rotate the camera\nwhile editing",\
                "Done","Back");
                if(listitem == 1) ShowPlayerDialog(playerid, DIALOG_CREATE, DIALOG_STYLE_INPUT, \

                if(listitem == 2) SelectObject(playerid);
            }
        }
        case DIALOG_CREATE:
