You have not punched cards, until you've punched them in the original Klingon.

Those header cards are punched for four-way symmetry so they can run in any direction, whether backwards or upside down. But they have so many punches that they’re almost lacy in appearance. ... Ummm ... 2-way symmetry (1<=>80) is easy; punch just 40 columns starting at each end. (12<=>9) harder in EBCDIC -- need to decode binary images (in an exit entered for each card). And if decoding binary, why punch the card symetrically -- let software do it. I once used a site where the job separator cards were brown stock with no corner cut; easily spotted by the operator. No symmetry; needed to be correctly oriented with the vendor's EOF code in column 1. Visual inspection by the operator may have had an adverse consequence. I once got punched output with *one* card punched in wrong orientation. Best explanation: That card was backward in the hopper and so punched. Operator separating jobs noticed the wrong corner cut and "fixed" it. I fixed it further by duplicating it in correct orientation on a keypunch. I once made an 81-column card by making minuscule adjustments at the punch station. Reader read 80 columns (FSVO) correctly and ignored the 81st with no error indication. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN DISCLAIMER: This email and any attachments may contain confidential information that is intended solely for use by the intended recipient(s).
