Who Should Use the Exercises?

These exercises have been written for LANSA developers who have completed the Visual LANSA Fundamentals training. Basic Repository and RDML programming skills are required. You should have completed the Visual LANSA User Interface Tutorial, Editor Tutorial, Repository Tutorial and the RDML Programming using Forms Tutorial before starting these exercises.

These exercises will expand upon the basic form programming skills learned in the Fundamentals tutorials.

How Many Developers Can Use the Exercises?

Except if you are using a trial version of Visual LANSA without a development license, there is no limit to the number of developers who may use the exercises at the same time in the same partition. However, it is important that each developer has a unique identifier for their own work as noted below.

If you have a development license:

  • To allow for more than one developer to do the exercises in the same partition, all LANSA object names are prefixed with iii which represents a unique three character code assigned to each exercise user. For example, if your name is John David Smith you can use the characters JDS. When asked to create a form named iiiVFW01, you will create a form named JDSVFW01.

    If you are completing more a LANSA exercise more than once, and you are asked to create another iiiVFW01 form, you can simply use a different set of characters for iii.
  • Always remember to replace iii with your unique 3 characters when creating objects in LANSA. You will not always be reminded to make this substitution.

If you are using LANSA in trial mode:

  • Only one developer can do the exercises in the same partition because object names must be unique. In trial mode, only a prefix of iii=DEM is allowed and components must be named DEMCOM01 to DEMCOM10. If objects DEMCOM01 to DEMCOM10 already exist, they must be deleted from the repository before you start these exercises.
