In the linux subdirectory of the tarball, there's a file called
'us5250.map'.  It contains all of the key definitions that we use
on the keyboards in the USA.   Maybe you could use that as a sample
of how to do it?

Mine shows:
string F21 = "\033[35~"
string F22 = "\033[36~"
string F23 = "\033[37~"
string F24 = "\033[38~"

What that means is that when you press F21 (for example) Linux will send
the string ESC [ 3 5 ~ to TN5250.

If you look at the file called 5250.terminfo (in the same directory)
you'll see this:
kf21=\E[35~

That means that the "kf21" terminfo capability is recognized when Linux
sends that sequence of characters.   In the man page for terminfo,
I see that "kf21" maps to the "FB" termcap capability.

In the src subdirectry of the tarball, I open up cursesterm.c.   Here I
see this:
  { K_F21, "FB" },

That means that when the sequence for the "FB" termcap capability is
pressed, TN5250 will recognize it as F21.

You'll note that most of my explanation is referring to Linux.  Only the
last bit (the cursesterm.c bit) is part of TN5250 itself.
