In principle the initialisation process especially for
the program CODING3 can take a lot of time. If you work with big overlay datasets and/or a big iteration
value, there also may be a time problem for the programs CODING1 and
CODING2. To reduce this time-consuming process, you can save the result of the
initialisation process in a dataset – the parameter dataset – to use it at
encoding or decoding time instead of the original key.
In extreme
cases (especially program CODING3) its possible that the initialisation process
takes up to several hours or even several days. Therefore you can save
intermediate results of the initialisation process and continue with this
initialisation process at later time using the intermediate results stored
before. To do this, the initialization process has to be limited.
