Slave Workstation

To complete this exercise you must be using Visual LANSA as a Slave Workstation. This means it can be connected to a Master LANSA system on an IBM i server, so that you can check in and check out Repository objects and execute a form in client/server mode against the IBM i server.

If you are using a free trial copy of Visual LANSA or Visual LANSA as a Standalone installation, you can complete the exercise but will only call the function as a Windows Application running on the desktop, with a local database.

Objective

• To demonstrate the EXCHANGE and CALL commands and the CALL_SERVER FUNCTION BuiltIn Function.

To do this:

• • You will create a simple form, Salary Review, which calls a function passing department code and a number that represents 'percentage salary increase'.
  • The called function will create a list of employees for the requested department, containing both current and new salaries based on the percentage increase. This results list is returned to the calling form.
  • The Salary Review form will display the result in a list view and calculates the total cost of the increase.
• The called function will be compiled for Windows and will also be checked in and compiled on the IBM i server.
• The Salary Review form will be tested in two different modes:
  • As a Windows Application running on the desktop, with a local database.
  • As a client to an RDMLX IBM i Server
• The form will use a system variable *SSERVER_CONNECTED (value Y or N) to determine whether to CALL the local function, or use CALL_SERVER_FUNCTION to call the function running on the IBM i server.

...

In order to achieve these objectives, you must complete the following:

Step 1. Create the Called Function

Step 2. Create Salary Review Form

Step 3. Add Form Logic

Step 4. Test Salary Review Application
