Bit 5-0 of second character are lower 6 bits
of card.
ASCII mode recognizes some additional forms of input which allows the
intermixing of binary cards with text cards.
Lines beginning with ~raw are taken as a number of 4 digit octal values
with represent each column of the card from 12 row down to 9 row. If there
is not enough octal numbers to span a full card the remainder of the
card will not be punched.
Also ~eor, will generate a 7/8/9 punch card. An ~eof will gernerate a
6/7/9 punch card, and a ~eoi will generate a 6/7/8/9 punch.
A single line of ~ will set the EOF flag when that card is read.
For autodetection of card format, there can be no parity errors.
All undeterminate formats are treated as ASCII.

Auto output format is ASCII if card has only printable characters
or card format binary.
