Description:
Many are confused about the difference between the LEVEL number that displays on the Panlib Member Selection List (MSL) and the term LEVEL.
Solution:
The LEVEL number on the MSL reflects every change you make in any way. If you enter and edit a member, save and then repeat this process multiple times in one edit session, the LEVEL will be incremented each time. This can be reflected in the member in the right columns depending upon settings.
VERSIONs are stored copies of the member. You can MATCH-MERGE a delete file to get multiple VERSIONs. Note that the PVOPT parameter DELVERS determines how many VERSIONS you can create so it must be greater than 0. (Please see page 5-52 of System Management Guide)
Here is very basic example with insignificant columns removed:
PVEDIT ---- TEST.PANLIB(ANEW)-----------------------------------------------

000600 after the ++DUMP I make more changes
000700 then perform a MATCH MERGE combining this PANLIB and the HISTORY file
000800 this will create a VERSION 2
