Typematic Delete Character; Enhanced Cursor Tab - IBM 3270 User Manual

the following null or space is not deleted. The cursor is left at its
current location. Attributes and the characters to the right of them
are not shifted. Subsequent rows are not shifted. If the cursor is
located under a null or a space, the null or the space is deleted.
If the cursor is located under an attribute, or if the cursor is located
in a protected field, input is inhibited and the Go Elsewhere

symbol is displayed in the operator information area.
3.2.6 Typematic Delete Character
The Typematic Delete Character key (Left and Right Brackets key
in ALT shift for U.S. keyboards) causes a delete function identical
with the current delete key except that this key is typematic.
3.2.7 Enhanced Cursor Tab
When the Tab key is pressed, the cursor moves to the next
unprotected tab stop, replacing unprotected null characters with
space characters. If there are no intervening tab stops, the cursor
moves to the next unprotected field; null characters are not changed
to space characters in this operation.
This capability does not wrap the cursor from the lower right to the
upper left of the screen.
Note: The Tab key operates differently when document mode is
enabled and tab stops are set than when document mode is disabled.
While in document mode with tab stops set, the Tab key introduces
data (space characters) into the data stream sent to the host
program. This insertion is necessary to preserve the tabular
formatting that appears on the screen. Many programs are unable
to handle this new data. Entry Assist is not intended for use with
these programs.
If
no tab stops are set, the Tab key operates in the
same manner, regardless of whether document mode is enabled or
disabled, except that it does not wrap the screen.
