In the product documentation, the notation vrs, vr, or simply v is often used as a placeholder for the current product version, for example, in data set or module names.

Placeholder | Meaning | Definition
--- | --- | ---
v | version | Major Version The first digit of the product version number indicates major architecture and functionality implementation or enhancement that adds value to the product.
r | release | Minor Version The second digit of the version number indicates functionality addition or enhancement that adds value to the product.
s | system maintenance level | Correction Level Correction levels contain error corrections only, without new functionality, including documentation of all modifications and repairs. In case it is necessary to include functional changes into a correction level, an exception handling process ensures that corresponding quality assurance activities are triggered. These functional changes are documented. The main target is to avoid impacts when you install such a correction level. The third number of an Adabas version denotes the system maintenance level. On certain platforms supported by Adabas, additional levels may exist, such as update package, patch level, service pack and hot fix.
