If the message exceeds the limits of the message box, either horizontally or

vertically, the portion of the message thatexceeds thelimits will not be displayed.

The message string itself is not altered. The entire message can be returned as a

query response regardless of what is displayed in the message box.

The message is left-justiﬁed, and is displayed on a single line starting with the

topmostlineinthewindow.Anewlinecharactercanbeembeddedinthestring

to position the message on multiple lines. You can also use white space and tab

characters to position the message within a line. Text which does not ﬁt within

the message box is truncated. Deﬁning a message box text string erases any

previously displayed text within the message box.

Youcan send a tab by transmitting a tab character (\t or \x09) followed characters

representing the most signiﬁcant eight bits followed by signiﬁcant eight bits of a

16-bit number. The number speciﬁes the position relative to the left margin of

the message area. For example, to tab send TAB (\t or \x09), NUL (decimal 0),

and CR (decimal 13).

For example, using hexadecimal escape sequences, MESSAGE:SHOW

’\x09\x01\x17Hello’ when sent as a command would cause the ’Hello’ to be

displayed starting at pixel position 279 relative to the left margin set by the

MESSAGE:BOX command. If you want to display characters starting at position

279, then 279 = 0x0117; split the hexadecimal number into two characters 0x01

and 0x17 and send \x09\x01\x17.

Special characters which control decorationare two character sequences where the

ﬁrst character is an escape (0x1b) and the second character is as described below.

Bit 7 0

Bit 6 If set, inverse video is toggled from current state and the following text

is displayed in the new inverse state until the state is toggled again.

Remaining bits are ignored

Bit 5 If set, the color index in the four LSB’s (bits 0 through 3) is applied to

the foreground or background color depending on the fg/bg bit (bit 4).

Bit 4 If set, color change is applied to the background, otherwise applies to

the foreground.

Bit 0 – 3 Speciﬁes thecolor index (0 through 15) to change color as speciﬁed

below:

Index 0 Black (background)

Index 1 Yellow(Ch 1)

Index 2 Cyan (Ch 2)

Index 3 Magenta (Ch 3)

Index 4 Green (Ch 4)

Index 5 Red (math)

Index 6 White (reference)

Index 7 Orange

Index 8 Gray (Graticule)
