ASCII APL CODES
There has been some discussion in this group about ASCII APL terminals.
I have mentioned that in my experience there are only two basic
translation tables needed to support all ASCII APL terminals. The
following table shows the differences between the two translations.
The codes used with these two terminals types are usually called
Key-pairing or Bit-pairing (just why, I'm not sure).
The following information should allow someone to convert a translation
table from one code to the other, or to make sure that both types of
ASCII APL terminals are supported by a given APL interpreter.
