* 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.
