How to Work with Processes > Working with the Host Services Processes Group

Process Purpose

The "Receive from Host" process is used to receive data packets from a specific Host server.

When you add a process, you are required to define its settings. This occurs in the process's properties window which is displayed automatically after having added the "Receive from Host" process.

If any subsequent edition is required, double-click the process to open its properties window and enter the necessary modifications.

Proceed as follows:

Host Options
Host Name	Select a host profile from the drop-down OR click to create a new host profile or edit an existing one. See To Create a Host Profile OR To Edit a Host Profile OR The <Default> Host Profile.
Packet Type	Select the packet type to be received from the Host. Either select it from the drop-down OR click and select a variable with that value. See Variable Usage.
Field Separator	Select the character to use as a field separator from the drop-down.
Packet Fields column	Click to select the variable that will receive the packet fields. See To Select/Create a Variable.
If Communication Error
Go to	Select a target location from the drop-down or list, in case there is a communications error. See Detail of a window below. When defining a screen as a target destination (ex: via a “Go to” process), you CANNOT use variables to specify the name of that target screen. You must select the intended screen from the available drop-down/list.

Use the editing icons to the right of the table to move the rows up and down and to delete or add more rows.

Detail of a window:

""S:Menu" is a screen included in the same program as the process.

"R:Routine_1" is a routine included in the same program as the process.

Use the following recurring icons (located on the upper right corner of the properties window) to execute specific operations:

•Click to define a time out. See Time Out.

•Click to attach any relevant notes to this process. Click it and enter your notes in the resulting text box. These notes will be displayed in the corresponding "Actions" tab or "Process" window (in the "Notes" field) and in the "Developer Report".

After filling in the required options, click to conclude or click to abort the operation.

The added process is displayed in the corresponding "Actions" tab or "Process" window.

If you want to use a label as a target destination, you can use the "Auto-Label" mechanism. This alternative to the "Set Label" process allows you to create a label in the properties window of a process - specifically, in the fields used to define target destinations (ex: the "If Error..." type fields). See To Automatically Create a Label.

Use the right-click in MCL-Designer's input boxes to access some related options as well as the general "Cut", "Copy"; "Paste"; "Search" actions (active/inactive according to the current context).

Ex: If you right-click the "Variable" input box (included in a "Conversion's" properties window), you are provided with general editing/search actions and other more specific options such as "Variable Select" (see "Variable Select"); "Variable Insert" (see "Variable Insert"); "Insert Special Character" (see To Insert Special Characters into a Control's Text Input Field) and "Localization Select" (see Localization List).

If you right-click another input box, it may provide other possibilities.
