Documentation

Definition

When all possible source values are known in advance, it is possible to generate coding that contains the relationship between the source value and the resulting offset. This indicator allows you to specify how the coding should be generated.

• Case structure
  Each possible source value is listed as a new case item with the resulting offset.
• Internal table
  The first time the action is performed, an internal table is created by determining the offset for all possible source values.

Use

• Case structure
  + The determination of the offsets is done on generation. At runtime no additional evaluation time is required.
  + The generated coding is easy to understand. Missing relationships can be detected.
  - The determination of the offsets is done on generation. Changes on the action definition always require a new generation.
  - Having a huge amount of possible source values, the generated coding for the case structure can become too big.
• Internal table
  + The determination of the offsets is done at runtime. Some changes on the action do not require a new generation.
  + The amount of generated coding is always the same. It is independent of the amount of possible source values.
  - The determination of the offsets is done once at runtime. For this additional runtime is required.
  - Because you cannot look into the internal table after generation, missing relationships are hard to detect.

When creating a new action, the case structure is good for testing. Afterwards the internal table is advisable because it keeps the coding small and some changes on the action do not require a new generation. The additional time for processing at runtime can be neglected.
