<DEL> Key Behaviour In TESS
6.5.5.2 <DEL> Key Behaviour In TESS
Field mode
• In a left justified field, the <DEL> key erases all characters in the
field and places the cursor in the left most position of that field.
• In a right justified field, the <DEL> key erases all characters in the
field and places the cursor in the right most position of that field.
• If the <DEL> key is used to clear data in a field that has been
pre-filled by the host application, the field is flagged as modified
and the updated information is sent to the host in the next response
message.
Replace mode
• In both left and right justified fields, the <DEL> key erases charac-
ters beginning from the current cursor position to the end of the
field. The cursor remains in the same position in the field.
• If the <DEL> key is pressed while cursor is in the right most
position in the field, the 7535 emits a keyboard error beep.
• If the <DEL> key is used to clear data in a field that has been
pre-filled by the host application, the field is flagged as modified
and the updated information is sent to the host in the next response
message.
Insert mode
• In both left and right justified fields, the <DEL> key erases the
characters from one character position to right of the cursor to
the end of the field.
• If the <DEL> key is pressed while the cursor is in the right most
position in the field, the 7535 emits a keyboard error beep.
• If the <DEL> key is used to clear data in a field that has been
pre-filled by the host application, the field is flagged as modified
and the updated information is sent to the host in the next response
message.
Fcursor mode
• Refer to “Field Mode” at the beginning of this table. The <DEL>
key operates in the same manner in “Fcursor mode” as it does in
“Field mode”.
