Re: hp2641a terminal query
Remember that there are two great ASCII<-->APL translations in the terminal
world, identified (by some) as BIT pairing and KEY pairing.  Any APL worth
its salt in the ASCII world must have some way of dealing with either
terminal type.  All the ordinary characters are the same in both, but
the special characters map differently (such as the parens, left and 
right arrows, times, divide, etc.).  When the APL program is started up,
there is usually some way to tell the program which kind of terminal
you are using.  On systems I am familiar with, the program asks the user
to type in an APL right paren (or grabs it from the invokation command).
This character identifies the terminal type being used.  On other systems
the user says either KEY or BIT, or names the terminal being used.

Check to see that the UNIX APL you are using is using the same translation
table type as your terminal needs.
