What can be the offset parameter for the code that extracts the user's comments from the VK?

Question

In contact with

Hello. There is an interesting procedure for execute (I reproduce the code for this topic below ), which allows you to extract the comments of a specific user from the communities - or all at once if the user_id parameter was not passed. It was never possible to find an acceptable digital step for sequential enumeration of pages without gaps, so that the next command would continue from the comment where the previous one stopped. Is it possible to somehow define the values ​​that the offset parameter can take ?

var owner_id = Args.owner_id;
    var user_id = Args.user_id;
    var offset = Args.offset;
    var post_count = Args.post_count;
    
    if (post_count == null)
        post_count = 10;
    
    // Получаем список постов
    var posts = API.wall.get({
        "owner_id": owner_id,
        "offset": offset,
        "count" : 100,
    });
    
    var i = 0;
    var userComments = {};
    
    while(i < posts.items.length && i < post_count)
    {
        var post_id = posts.items[i].id;
        var comments = API.wall.getComments({
            "owner_id": owner_id,
            "post_id": post_id,
    
            "count" : 100,
        });
    
        var j = 0;
        while(j < comments.items.length)
        {
            if (user_id == null || comments.items[j].from_id == user_id)
                userComments.push(comments.items[j]);
    
            j = j + 1;
        }
    
        i = i + 1;
    }
    
    return userComments;
