HOLDDATA involves a CAIRIM refresh and user program re-assemblies. This article clarifies the order in which these tasks can be performed.
SO05694 replaces APFLIB module RHDCSSFM, several "normal" IDMS system modules (non-APFLIB), and some DSECTs.

Care must be taken in the order in which the various modules can be deployed.
