Block Mode

The Tandem 6530 emulation operates in one of three main modes:
Conversational, Block, or ANSI. Conversational and Block modes
are normally used for applications running on a NonStop host
system. ANSI mode is for applications running on the LXN host
system.
In Conversational mode, characters are sent to the host as you type
them. This is useful when applications need to interact with you on a
character, word or line-by-line basis.
Display memory is treated as one long page consisting of 400 lines,
of which 24 lines may be viewed at any one time. Lines above or
below those currently displayed may be scrolled into view using cur-
sor or display control keys. Once all the display memory has been
used, new data will force all previous lines of data up one line so that
the first line is erased, ensuring that the oldest data is erased first.
The status line will display
mode.
In Block mode, characters are stored in a communications buffer and
are not transmitted to the host until the application requests them.
The characters are then sent as a block. This enables you to enter a
large amount of data and edit it locally before it is transmitted.
Block mode has two sub-modes: Block Nonprotect and Block Pro-
tect. In Block Nonprotect mode you can enter any type of character
at any position on the screen (except on the 25th line). In Block Pro-
tect mode the application divides the screen into protected and non-
protected areas called fields. The cursor cannot be moved into
protected fields, which may contain prompts or information or be
empty. The cursor can only be moved into unprotected fields, which
may also define the type of characters that can be entered.
In Block mode, display memory is divided into pages, the number of
pages being determined by the application.
