50 * Read one line of standard input and produce something that looks like a
51 * punch card. An attempt to reimplement /usr/games/bcd. All I looked at
54 * I couldn't find a BCD table handy so I wrote a shell script to deduce what
55 * the patterns were that the old bcd was using for each possible 8-bit
56 * character. These are the results -- the low order 12 bits represent the
57 * holes. (A 1 bit is a hole.) These may be wrong, but they match the old
61 * sahayman@iuvax.cs.indiana.edu
65 * I found an error in the table. The same error is found in the SunOS 4.1.1
66 * version of bcd. It has apparently been around a long time. The error caused
67 * 'Q' and 'R' to have the same punch code. I only noticed the error due to
68 * someone pointing it out to me when the program was used to print a cover
69 * for an APA! The table was wrong in 4 places. The other error was masked
70 * by the fact that the input is converted to upper case before lookup.
