Message/Status
Line
The bottom row of the screen contains the message/status line, which has
the following format:
Columns 1 and 66 always contain a blank space.
The message area occupies columns 2 through 65. It can contain any
character string sent through an escape sequence from either your
application program or the keyboard in conversational mode.Text in the
message area remains visible until it is cleared or reset by another escape
sequence.
The status area, occupying columns 67 through 80, contains terminal
status information such as the current mode of operation. Only the 6530
can write into this area; your application cannot address this area. The
user can enable and disable the display of the status area by pressing the
Ctrl-Next Page and Ctrl-Prev Page keys, respectively.
Error Line When the 6530 detects an error, it temporarily replaces the message/
status line with an error line. The error line has the following format:
These types of error can occur:
General errors. Operator errors, device errors, and other errors
detected by the operating system or by the 6530.
Communications errors. Invalid commands to the 6530 (detected
and reported by the Command errors).
While the error line is displayed, any keypress removes the error line and
restores the message/status line.
