# TechTip: Dynamic Menu Using Tree Data Structure

###### Typography

This method for deploying menus uses only three objects to represent as many menus as needed. And menus can be changed by editing the file's records, instead of the code.

Here, we present an alternative method for deploying menus in IBM i. All menus in our system can be stored in one DDS file and displayed by an array-subfile program. Each menu is stored as a tree-like form in the DDS file. Thus, the Dynamic Menu program can assign a menu with its options and can be easily navigated.

## Graph and Tree Data Structure Theory

The Tree Data Structure (T-DS) is one of the most powerful data structures; it's often used in advanced tasks such as AI and compiler design [2, 3, 4]. Rooted trees can be used to store data in the computer's memory in many different ways. Unlike array, linked list, stack, and queue, which are linear data structures, tree is a hierarchical data structure. But what exactly is a tree? A graph is considered a set of vertices/nodes, which represent objects, data, or even operations, and edges/links, which represent links between the nodes.

A tree is a special kind of graph that follows a particular set of rules and definitions (Figure 1):

• ConnectedA graph can be a tree if it is connected. Each node is connected with a link to at least one other node.
• AcyclicA graph can be a tree if is acyclic. That means there's only one route from any node to any other node.
• Root: The term root commonly refers to a top-most node. In Figure 1, node F is the root of the tree.
• DescendantA descendant is a node that is farther away from the root than some other node. The term descendant is always in reference to another node. In Figure 1, nodes I and H are descendants of node G.
• ParentParent is considered the node that is closer to the root node by one link or vertex. In Figure 1, node B is the parent of nodes A and D.
• SiblingSibling nodes share the same parent. In the example, nodes A and D are siblings.
• AncestorAn ancestor is any node between a given node and the root, including the root. In the example, the ancestors of node H are nodes I, G, and F.
• Leaf or Terminal NodeA node is terminal if it has no children. In the example, node C is a leaf.
• HeightThe height of a tree is defined as the number of vertices traversed to get to the most distant node. In Figure 1, the height of the tree is equal to three.

Figure 1: This is an example of a tree data structure.

In menus, information naturally forms a hierarchy; objects are ordered "above" or "below" other objects. Tree data structure is a very efficient way to represent this type of information. In the problem at hand, each menu is a rooted tree. Root can represent the base menu while descendants of the nearest lower level can represent the options of the base menu. In this TechTip, nodes represent menu's options and new sub-menus, while leafs represent programs.

To store information in a hierarchical manner, a DDS file with the following fields will be used. Each record in this file represents one vertex (node or leaf) of the tree.

• DYNFUNCT (not unique key)Since Dynamic Menu is designed to hold all of our system's root menus, we need a field to classify the records and assign them to a specific root menu. This segregation can be done based upon this field.
• DYNSTYPEThis field holds the record's type. A record can be either node type (new sub-menu) or leaf type (program to be called or command).
• DYNSCODEThis is the record's code ID. If this record is a leaf type record, it holds the name of the program that will be called. If this record is a node record, it holds the name of the new sub-menu.
• DYNCFROMThis field displays the node (menu or sub-menu) in which this record belongs. In other words, this field holds the code ID of this record's parent node.
• DYNLEVELEach record has a level. For example, root record belongs to the first level.
• DYNSDESC This field is the option's brief description. If the record is a root menu or sub-menu, this description is shown as screen header.
• DYNSSORTThis is for the menu options order. For example, the record with sort value equal to 2 will be displayed higher than its sibling record with sort value equal to 5.

Listing 1 shows an example of the DDS file code. Of course, the file and the logic can be expanded to deal with authority issues or to call leaf programs with additional input parameters, commands, etc. See the example data displayed in Listing 2.

Listing 2: Example of file's data

The program that manipulates the file's data is in essence an array-subfile program [5]. The dynamic menu (DMenu) program uses one main array as a pool and one screen array to fill the screen subfile. Initially, all records related to the root menu are loaded in a main array. Each time, the dynamic menu program reads the appropriate records from the main array and creates a subfile of output records via the screen array. When the entire subfile is written, the program sends the entire subfile to the display device [6]. The flow diagram is displayed in Figure 2. Please note that this TechTip is not intended to explain how an array-subfile program works.

Figure 2: Dynamic menu flow diagram

As mentioned before, the dynamic menu can be used to display all menus in a system. Thus, DMenu should be called with at least one input parameter (of course, entry parameters can be expanded to return errors or messages to the previous program, etc.) in order to select only the records that are needed for the specified root menu.

Two basic arrays are used. Initially, all records related with the root menu are loaded in the main array. In addition, all option records related with a sub-menu (or root menu) are loaded to the screen array in order to be displayed on screen. The options from the screen array are loaded to the screen subfile. The screen heading is loaded from the description of the submenu's (level one) root record. An example of the arrays definition is shown in Listing 3.

Listing 3: Main and Screen arrays definition in D-spec

When a user selects an option, the program will check the field that shows the type (DYNTYPE) of the corresponding record to see if the option is a node (value 'N') or a leaf (value 'L'). When the option is a leaf, DMenu calls the program whose name appears in the code ID field (DYNSCODE) of the option's corresponding record. On the other hand, if the option is a node, screen array is reloaded with root record equal to the corresponding record of the user's option.

Let's look at the following example, which is based on the data of Listing 2. Call the dynamic menu with the appropriate input value (Listing 4):

Listing 4: Calling the dynamic menu

All records from the DDS file are copied to the main array. This is happening because the DYNFUNCT field value is equal to 950030 in all records. Thus, all records in the DDS file belong to only one root menu. The root record's description is displayed in the screen's header, while the records that are assigned to the root menu (e.g., rrn: 2 to 6, DYNCFROM = "APSMN01") are passed to the screen array. The screen array is sorted by the DYNSSORT field. The screen subfile is filled by the screen array (Figure 3).

By selecting option 3, the procedure is repeated. The description of the Sub-Menu 2 is displayed in the screen's header, while the records that are assigned to this sub-menu (rrn: 7, 8) are passed to the screen array. The screen array is sorted by the DYNSSORT field, and it fills the screen's subfile (Figure 4).

When the user presses F12-Cancel, the program searches the main array for the corresponding record of the Sub-Menu 2 node. That is, it searches the record with a DYNSCODE value equal to APSMN03, which is the code ID of the Sub-Menu 2 node. The new menu is defined by the DYNCFROM value. The root menu screen is diplayed again (Figure 3).

Of course, there are many ways to implement the code of a dynamic menu. The following snippets of code constitute a simple DMenu creation example.

As mentioned before, initially the main array must be loaded with all the root menu's related records. Listing 5 shows a code snippet for loading the main array from the file, where variable InpEntry is the program’s input parameter (e.g., 950030) and DYN00L4 is a logical file with one key (DYNFUNCT). The code ID of the root menu record is stored in the FirstScreen global variable.

Listing 5: Load Main array example.

The screen array's loading procedure can be called with the menu's code ID as an input parameter (e.g., FirstScreen variable). This procedure is divided in two sections (Listing 6). The first section is responsible for filling the screen array if the input node is a root node, while the second section is responsible for filling the screen array in every other case. At the end, the screen array is sorted by the DYNSSORT file's sort field. In addition, a fold/unfold indicator is used to leave a blank between the menu's options. If the menu doesn't have many options (e.g., '7' in this example), then this indicator goes *On and the subfile displays the options with a blank record between them (Figure 3).

## Summary

This TechTip presents an alternative method for deploying menus in IBM i. In IBM i, each menu is composed of three different types of objects (*MSGF, *FILE, *MENU). Each time we need to maintain a menu, we have to edit the code and recompile the objects. Instead of creating different objects with different source types for each different menu, by employing the proposed method we need only three objects (one screen, one program, one file) to represent as many menus as we like. All the menus are stored in one DDS file, and we can edit them without an intervention in the code. Finally, this method prevents the repeated programs' call, resulting in better performance and in avoiding the "many calls" limit.
