STCKs are low-level commands which cannot be intercepted and therefore pose more of a problem. Load module integrity is maintained and version management is simplified. However, any assembler programmer could issue a STCK instruction. DynaMod scans the designated load module after it is brought into memory. Since we are not modifying the load module itself, the integrity of the load module is maintained and its quality is assured.
Version management is simplified.
If load modules are modified, additional versions may be created for backup or security reasons. Managing these versions would become an additional production responsibility. The use of DynaMod eliminates this need. Most major applications include a number of batch jobs, often involving passing datasets from one to the other. In production, they are often defined as a Net to the system scheduler with a definition of precedence relationships or indications that certain jobs or steps can run in parallel.
