Numeric variable
The numeric variable is a decimal number represented as an
ASCII string. Some commands allow the string to be preceded
by a plus (+) or minus (-) sign, and others allow the number to
include a fractional part after a decimal point represented by the
full stop (.) character. If the numeric variable is not provided, it
is assumed to be zero.
Parameter character
The parameter character indicates the parameter to which the
previous numeric variable applies. The parameter character is
only used when several escape sequences are combined. The
parameter character may be within the range of hexadecimal
60—7E (decimal 96—126), and is a lowercase version of the final
parameter.
Final parameter character
The final parameter character, which also references the previous
numeric variable, is used to end an escape sequence. The final
parameter character is always uppercase.
Table 3-2 summarises the use of parameter and final parameter
characters.
