- The main problem with documenting how MAP3270.DAT works, is that what you
- specify in the file for a key definition depends on what ASCII codes
- particular keys on your terminal generate. A "^A" is (pretty much) guaranteed
- to send the same ASCII code (001) by any terminal. However, what "F1" sends
- might be different for different terminal types.

- A DEFINE /KEY function would be nice; I'll put that into our list of projects.
- It'll take some special thought, however, to figure out how to do it for the
- normal command line of FTP, MU CONFIG, etc. as well as for TN3270.
-
- A user exit for the end of a word? Bleah. I've spent a brief bit of time
- looking through the code, and it's pretty hairy. Have to think about that
- some...
