* bcd --

*
* 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

*
* 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.
