They do the obvious thing to their argument. .SH "HOLLERITH CHARACTER TABLE" .IX Header "HOLLERITH CHARACTER TABLE" A Hollerith string is a sequence of 12\-bit characters; they are encoded as two \s-1ASCII\s0 characters, containing 6 bits each: the first character contains punches 12, 0, 2, 4, 6, 8 and the second character contains punches 11, 1, 3, 5, 7, 9; interleaving the two characters gives the original 12 bits. To make the characters printable on \s-1ASCII\s0 terminals, bit 7 is always set to 0, and bit 6 is set to the complement of bit 5. These two bits are ignored when reading Hollerith cards. .PP Some Hollerith characters (produced by overpunching) can be converted to sequences of \s-1ASCII\s0 characters; \fIascii2hollerith\fR will correctly recognise the sequences. .PP The following punched cards document the encoding of characters (the last three symbols at the end nongraphic symbols in \s-1ASCII\s0; the previous two symbols correspond to multicharacter sequences): .PP .Vb 10 \& \*(Aq !"#$%&()*+,\-./:;<=>?@[\e]^_\`{|}~XX0123456789 \& 12 * * * * * * * * * * 12 \& 11 * * * * ** ** * * * 11 \& 0 * * * * **** * * *** 0 \& 1 * * * 1 \& 2 * * * * * 2 \& 3 ** * * * * 3 \& 4 *** * * ** * * * * 4 \& 5 * * * * * * 5 \& 6 * * ** * * 6 \& 7 * *** * * 7 \& 8 * ******** * * ******* * * * * * 8 \& 9 * * * 9 \& \& ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrs \& 12 ********* ********* 12 \& 11 ********* ********* 11 \& 0 ********* * * 0 \& 1 * * ** ** * 1 \& 2 * * * ** ** * 2 \& 3 * * * ** ** 3 \& 4 * * * ** ** 4 \& 5 * * * ** ** 5 \& 6 * * * ** ** 6 \& 7 * * * ** ** 7 \& 8 * * * ** ** 8 \& 9 * * * * * 9 \& \& tuvwxyz [] ".
