Backtab key. When the cursor is located in the attribute character
position or the first location of an unprotected field or in any
character position of a protected field, this key moves the cursor to
the first location of the first preceding unprotected data field. When
the cursor is located in a location of an unprotected field other than
the first location, this key moves the cursor to the first character
location of that field. In a display with no unprotected fields, the
cursor is positioned to row 1, column 1. (Esc i performs Backtab key
functions.)
Enter key. If this key is set as a function key, its behavior is
unchanged. Otherwise it moves the cursor to the first unprotected
character location of the next line. If the display has no unprotected
fields, the cursor is positioned to row 1, column 1. If the display
contains no fields, the cursor is positioned at the first character
location on the next line. (See the next section, “Unformatted
Mode.”)
Home key. This key moves the cursor to the first unprotected
character position on the screen. If the display has no unprotected
fields, the cursor is positioned to row 1, column 1. (Esc H performs
Home key functions.)
Home Down key. This key moves the cursor to the first location of
the last unprotected field on the screen. If the display has no
unprotected fields, the cursor is positioned at row 24,
column 1. (Esc F performs Home Down key functions.)
Unformatted Mode
In EM3270 mode, a screen with no fields is treated as a single
unformatted field. Data may be keyed at any character position. The
following escape sequences handle such a screen by transmitting any
character position not containing a null:
Esc < Read Whole Page
Esc = Read with Address
Esc ] Read with Address All
These data are not preceded by a DC1 row column sequence.
