Characters used in control functions appear in monospaced type. The following table explains
some of the conventions used.
A pair of numbers separated by a slash (/) character indicates Column/Row notation. This
notation refers to the location of a character in a standard code table, such as ASCII.
Spaces appear between characters in sequences for clarity; they are not part of the format. Space
is designated as "SP" when it is part of the format of a command or sequence.
The following conventions are used in the command listings:
Conventions
Code Description
ESC
Escape (1/11), introduces an escape sequence.
CSI
Control Sequence Introducer (9/11), intoduces a control sequence. CSI can also be represented
by the equivalent escape sequence ESC [ (1/11 5/11).
DCS
Device Control String (9/0), introduces a device control string. DCS can also be represented
by the equivalent escape sequence ESC P (1/11 5/0)
ST
String Terminator (9/12) indicates the end of a control string. ST can also be represented by
the equivalent escape sequence ESC \ (1/11 5/12).
Pn
Numeric parameter, or number of units that specify a distance or quantity pertaining to the
escape sequence, control function or control string.
Ps
Selective parameter, or one which identifies a list of options pertaining to the specific
command. If ">" (3/14) or "?" (3/15) occurs at the beginning of a string of parameters, the
following parameters are Digital private parameters. ">" or "?", if present must occur only
once at the beginning of the parameter string.
I
n
Intermediate character - component of an escape sequence, control sequence or control string.
F
Final character - component of an escape sequence, control sequence or control string
SP
Space (2/0)
C0 Control Characters are given in figure "Standard 8-bit Code Table (Left Half)".
C1 Control Characters are given in figure"Standard 8-bit Code Table (Right Half)".
In the 7-bit environment, C1 Control Characters can be sent with an escape sequence provided
in the following tables.
Both numeric and selective parameters are interpreted as unsigned decimal integers, with the
most significant digit sent first. For instance, the value 16 is coded as "16" (3/1 3/6). Leading
zeros are allowed but are ignored. Plus and minus signs are not allowed.
