Thanks for the reply. I got to the point where I could test for
individual letter keys, but I'm still having trouble with the arrows.
If I try to test for the characters that correspond to the arrow keys,
like ┤:
test_pic_char =: 3 : 0
if. sysdata = '┤' do.
wd 'setxywh pic 0 0 150 150'
end.
)
I get a 'length error' when the program runs. Any ideas?

The datatype of sysdata is always character. The numbers shown are the
indices of the character values in a. (alphabet).
You can just press a key, observe the value of sysdata, and then program
for that value.
