Question

Environment name:  COB_BELL
  Parameter name:  bell
         Purpose:  Defines how a request for the screen to beep is handled
            Type:  FLASH, SPEAKER, FALSE, BEEP
         Default:  BEEP
         Example:  BELL SPEAKER

Environment name:  COB_REDIRECT_DISPLAY
  Parameter name:  redirect_display
         Purpose:  Defines if DISPLAY output should be sent to 'stderr'
            Type:  boolean
         Default:  false
         Example:  redirect_display Yes

Environment name:  COB_SCREEN_ESC
  Parameter name:  screen_esc
         Purpose:  Enable handling of ESC key during ACCEPT
            Type:  boolean
         Default:  false
            Note:  is only evaluated if COB_SCREEN_EXCEPTIONS is active
         Example:  screen_esc Yes

Environment name:  COB_SCREEN_EXCEPTIONS
  Parameter name:  screen_exceptions
         Purpose:  enable exceptions for function keys during ACCEPT
            Type:  boolean
         Default:  false
         Example:  screen_exceptions Yes

Environment name:  COB_TIMEOUT_SCALE
  Parameter name:  timeout_scale
         Purpose:  specify translation in milliseconds for ACCEPT clauses
                   BEFORE TIME value / AFTER TIMEOUT
            Type:  integer
                   0 means 1000 (Micro Focus COBOL compatible), 1 means 100
                   (ACUCOBOL compatible), 2 means 10, 3 means 1
         Default:  0
            Note:  the minimum and possible maximum value depend on the
                   screenio library used
         Example:  timeout_scale 3

Environment name:  COB_INSERT_MODE
  Parameter name:  insert_mode
         Purpose:  specify default insert mode for ACCEPT; 0=off, 1=on
            Type:  boolean
         Default:  false
            Note:  also sets the cursor type (if available)
         Example:  insert_mode Y

Environment name:  COB_MOUSE_FLAGS
  Parameter name:  mouse_flags
         Purpose:  specify which mouse events will be sent as function key
                   to the application during ACCEPT and how they will be
                   handled
            Type:  int (by bits)
         Default:  1
            Note:  0 disables the mouse cursor, any other value enables it,
                   any value containing 1 will enable internal handling (click
                   to position, double-click to enter).
                   See copy/screenio.cpy for list of events and their values.
           Alias:  MOUSE_FLAGS
         Example:  11 (enable internal handling => 1, left press => 2,
                       double-click => 8; 1+2+8=11)

Environment name:  COB_MOUSE_INTERVAL
  Parameter name:  mouse_interval
         Purpose:  specifies the maximum time (in thousands of a second)
                   that can elapse between press and release events for them
                   to be recognized as a click.
            Type:  int (0 - 166)
         Default:  100
            Note:  0 disables the click resolution (instead press + release
                   are recognized), also disables positioning by mouse click

Environment name:  COB_DISPLAY_PRINT_PIPE
  Parameter name:  display_print_pipe
         Purpose:  Defines command line used for sending output of
                   DISPLAY UPON PRINTER to (via pipe)
                   This is very similar to Micro Focus COBPRINTER
            Note:  Each executed DISPLAY UPON PRINTER statement causes a
                   new invocation of command-line (= new process start).
                   Each invocation receives the data referenced in
                   the DISPLAY statement and is followed by an
                   end-of-file condition.
                   COB_DISPLAY_PRINT_FILE, if set, takes precedence
                   over COB_DISPLAY_PRINT_PIPE.
           Alias:  COBPRINTER
            Type:  string
         Default:  not set
         Example:  print 'cat >>/tmp/myprt.log'

Environment name:  COB_DISPLAY_PRINT_FILE
  Parameter name:  display_print_file
         Purpose:  Defines file to be appended to by DISPLAY UPON PRINTER
            Note:  Each DISPLAY UPON PRINTER opens, appends and closes the file.
            Type:  string       : $ is replaced by process id
         Default:  not set
         Example:  display_printer '/tmp/myprt.log'

Environment name:  COB_DISPLAY_PUNCH_FILE
  Parameter name:  display_punch_file
         Purpose:  Defines file to be created on first
                   DISPLAY UPON SYSPUNCH/SYSPCH
            Note:  The file will be only be closed on runtime exit.
            Type:  string       : $ is replaced by process id
         Default:  not set
         Example:  display_punch './punch_$.out'

Environment name:  COB_LEGACY
  Parameter name:  legacy
         Purpose:  keep behavior of former runtime versions, currently only
                   for setting screen attributes for non input fields
            Type:  boolean
         Default:  not set
         Example:  legacy true

Environment name:  COB_EXIT_WAIT
  Parameter name:  exit_wait
         Purpose:  to wait on main program exit if an extended screenio
                   DISPLAY was issued without an ACCEPT following
            Type:  boolean
         Default:  true
         Example:  COB_EXIT_WAIT off

Environment name:  COB_EXIT_MSG
  Parameter name:  exit_msg
         Purpose:  string to display if COB_EXIT_WAIT is processed, set to ''
                   if no actual display but an ACCEPT should be done
            Type:  string
         Default:  'end of program, please press a key to exit' (localized)
         Example:  COB_EXIT_MSG ''
