I'm not so "young" to remember that, however I vaguely remember I read
some VSAM book (bought for many $$$). The book was awfully outdated, so
I learned mostly VSAM history and obsolete features. It was ~13 years
ago, but I would bet VSAM was born in 1974.

VSAM was no later than 1975. I was in a PL/I class at Sudbury in 1975.
Happened to be the week England beat Cyprus at Wembley 5-0 and Malcolm
MacDonald scored all 5 goals.
Anyway, our teacher at Sudbury asked this question:
"Why is VSAM like a cow in the middle of a meadow".
Answer:
"They are both outstanding in their field".
16 April 1975: England's Malcolm Macdonald scores five against Cyprus
Funny how things stick in your memory.
We were still ISAM many years later.....

I think CVOL / VSAM catalogs in MVS was version 1. ICF catalogs
introduced during XA switchover period is version 2.

This is just a curiosity question, but I’ve wondered about this.
The JCL reference says:
All temporary data set names begin as follows:
SYSyyddd.Thhmmss.RA000.jjobname
Does anyone know the story behind the ‘RA000’ part? It seems unnecessary
and arbitrary.
Well, we used to answer "Frankie did this and he said >> do't change it<<
but Frankie died..."
BTW: almost every LISTCAT output contains "VERSION: 2" statement. Why
it's
2?
