I have never used punched cards, so forgive me my questions.
As far as I know, a character set on punched cards was somehow limited, so it is not EBCDIC or similar set of 256 characters. Of course that means some limitations for DD * datasets - if coded on real punched cards. Nowadays I'm pretty sure DD * accept every possible character, as any other dataset (with some exception for delimiter). Note, it is program independent - this is a change within system (JES2, Interpreter, whatever).
Q1: how it was in the past? I mean, were the DD * limited to "punched card" character set? Or it was always full EBCDIC if the job was read from DASD?
Q2: What about character set on the cards? Was it always one and the same within S/360 family? I noted there were several character sets, but as far as I understand those set was for other machines (Remington, pre-S360 IBM machines, etc.) Was there any name for card character set? I mean something like "CP 037" or so.
And another question, or rather kind request: Does anynone have JCL statements on punched cards? I would like to get/download some images of JOB, EXEC, and DD statements on punched cards. I have a lot of card pictures, but none with JCL.
