> thousands of punched cards with no real way to read them anymore In this day and age it should be pretty trivial to write software that would encode a scanned image of a punched card.

The historical society that I'm a member of has thousands of punched cards with no real way to read them anymore. To compound not being able to read the punches these cards also contain handwritten data on each card. We have cards that contain train crew records, static data like employee name, employee number, employee phone number and other stuff. Handwritten data appears to be a months' worth of dates for when they worked that month/day. We also have cards that contain train movements. The punched data would be for a symbolled train and it starting location with time of call and a destination location. Handwritten info would include employees name for (Engineer, Fireman, Conductor, Flagman, Brakeman). All of these cards are from 1972-1975. My point is that punched cards were used for many different reasons and many different ways. If I remember correctly the Western Maryland Railway was one of the first if not the first railroad to incorporate the use of IBM computers and punched card.

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. -- Radoslaw Skorupka Lodz, Poland ====================================================================== Jeśli nie jesteś adresatem tej wiadomości: - powiadom nas o tym w mailu zwrotnym (dziękujemy!), - usuń trwale tę wiadomość (i wszystkie kopie, które wydrukowałeś lub zapisałeś na dysku).
