Ah, reminiscences.

The only program I ever wrote that worked to spec first time and 
never needed any de-bugging or correcting was ...

Do while there are pairs of cards in the card-reader:
    Read two cards, each of 80 columns
    Concetenate the first card and the first 52 columns of the second
    Write a 132-column line on the line-printer

(That's reasonable pseudo-code, by the way).

It sounds easy (8 *chars* of APL maybe? - maybe not, because APL was 
I/O-poor;  30 chars of grep?;  5 lines of Pascal?).  But it still 
took a remarkable number of cards full of obligatory lines of COBOL - 
40 or so?

We're talking 1971, by the way.
