Answer Posted / sukumar
The generation and version numbers are in the form GxxxxVyy,
where xxxx is an unsigned 4-digit decimal generation number
(0001 through 9999) and yy is an unsigned 2-digit decimal
version number (00 through 99).
For example:
A.B.C.G0001V00 is generation data set 1, version 0, in
generation data group A.B.C.
A.B.C.G0009V01 is generation data set 9, version 1, in
generation data group A.B.C.
The number of generations and versions is limited by the
number of digits in the absolute generation name; that is,
there can be 9,999 generations. Each generation can have 100
versions.
