 * bcd --

 * Read one line of standard input and produce something that looks like a
 * punch card.  An attempt to reimplement /usr/games/bcd.  All I looked at
 * was the man page.
 *
 * I couldn't find a BCD table handy so I wrote a shell script to deduce what
 * the patterns were that the old bcd was using for each possible 8-bit
 * character.  These are the results -- the low order 12 bits represent the
 * holes.  (A 1 bit is a hole.)  These may be wrong, but they match the old
 * program!

 *
 * I found an error in the table. The same error is found in the SunOS 4.1.1
 * version of bcd. It has apparently been around a long time. The error caused
 * 'Q' and 'R' to have the same punch code. I only noticed the error due to
 * someone pointing it out to me when the program was used to print a cover
 * for an APA!  The table was wrong in 4 places. The other error was masked
 * by the fact that the input is converted to upper case before lookup.
