@ twosleepy: Punch cards were just an input medium. One can no more tell what language you were using then one could if you had said you used a USB keyboard. My favorite punch card story is of the time I was filling in for the operators in the computer room and I fed a stack of punch cards into the reader without putting the weight in the output bin. My reaction times have always been pretty good so there were only about 100 or so cards spewed all over the floor after I hit the stop button. Fortunately the programmer had been smart enough to use sequential numbers in the first columns of the punch cards so all he had to do was read them in as pure data, sort by the first columns, and re-punch the resulting file.
@ ledasdottir: If knits are zeroes and purls are ones why is it called knitting? It should be called purling. Or either that or knits are ones, one.
