I think a box of 2000 IBM cards is on the order of 6 pounds, so a TON of JCL cards would be 333 boxes, or about 666,666 card images.

[was:RE: Straightforward way to determine hardware architecture level?] Re: "ton" of JCL, at least one large shop of my prior acquaintance (20 or so years ago) had over 250,000 members in the production applications JCL libraries. Not sure how much of that was obsolete at the time, but the batch operations control product they used had vast quantities of data as well.
