I tried the left arrow and still doesn't clear the character, it deletes it 
from memory but it leaves it on the screen, same as ctrl-h, when I use 
Wyse50 emulation on SCO unix, it works great, but not in linux. what can I 
do so that within filepro , when the user presses the BACKSPACE , besides of 
eliminating the last character itactually refreshes the screen so it's not 
shown anymore.

I checked the /etc/termcap file but it's more encrypted than sendmail's 
sendmail.cf mail rule file.


Thanks
