Issue/Introduction

Many are confused about the difference between the LEVEL number that displays on the PANLIB Member Selection List (MSL) and the term VERSION.

 

 

Environment

Release: 14.6
Component:   Panvalet

Resolution

The LEVEL number on the MSL reflects every change make in any way. If a member is edited, saved and the process is repeated multiple times in one edit session, the LEVEL is incremented each time. 

 

VERSIONs are stored copies of a member on a Protection file.  The MATCH-MERGE process is used to create a Protection file with multiple VERSIONs.

     *  Note if multiple versions are required the PVOPT parameter DELVERS must be greater than 0 and determines how many VERSIONS are retained on the Protection file.

 

Here is very basic example with insignificant columns removed:
