On some AS400 applicaitons the backspace key will move the cursor back without clearing the fields as it moves back and will leave the data on the screen. To get the backspace to delete the characters as it trails backwards you can create a macro that will perform a backspace + delete on press of the backspace key. This macro is set up in the emulation parameters under Emulation>common>key macros. The macro is: 0008:\0008\5300. This equals the hex values of Backspace=backspace+delete.
