Abstract

Disclosed is a method for making input of tables and character graphics easier on 3270 terminal emulation software which runs on a personal computer. The number of keystrokes required to create character graphics or tables is reduced by adding 3 new operational modes in which characters can be entered from right to left, top to bottom, and bottom to top respectively in addition to the ordinary left to right direction.

Free-Direction Character Input on 3270 Terminal Emulation

      Disclosed is a method for making input of tables and character
graphics easier on 3270 terminal emulation software which runs on a
personal computer.  The number of keystrokes required to create
character graphics or tables is reduced by adding 3 new operational
modes in which characters can be entered from right to left, top to
bottom, and bottom to top respectively in addition to the ordinary
left to right direction.

Four key functions are prepared:
  o  left to right input
  o  right to left input
  o  downward input (or top to bottom input)
  o  upward input (or bottom to top input)

      These key functions can be assigned to any keys on the keyboard
by using the emulation software's key remapping capability.  For
example, 'downward input' can be assigned to the alternate shift
position of the 'cursor move down' key.  Once this key is depressed,
the emulation software enters into 'top to bottom input' mode; the
next depression of the same key restores the mode to the default,
i.e., 'left to right input' mode.  The mode restoration is also
possible by depressing a key which has been assigned the 'left to
right input' key function.

      The four input modes have effect only on character keys
(including space key) which are used to enter alphabet letters,
numerals, and special characters; the modes have no effect on
function keys such as Program Function (PF) keys, Enter key, Clear
key, shift keys, and so forth.

      When one of the character keys is depressed, the corresponding
character is placed at current cursor position, and then the cursor
is moved to the next input position which is dependent on the current
input mode:
  left to right input mode:   immediately right to the current
position
  right to left input mode:   immediately left to the current
position
  downward input mode:        immediately below the current position
  upward input mode:          immediately above the current position

      (To simplify the description, the case that the next input
position defined above exceeds the screen boundary is ignored here.)

      Insert mode (depressing Insert key enables this mode) is
effective only in the 'left to right input' mode.  When one of the
input mode keys other than 'left  to right input' is depressed in the
insert mode, the insert mode is disabled, but restored effective when
'left to right input' mode is resumed.

      The auto-skip function is effective only in the 'left to right
input' mode.

      (Auto skip function: moves the cursor to the  next unprotected
field when a character is entered at the last position of an
unprotected field.  Field att...
