Model 880 Command Descriptions
The following paragraphs describe the Model 880 emulation mode
commands. Many of the escape-sequence commands contain one or
more variables to specify various command parameters. These
variables are italicized in the command formats to indicate that they
can be set to more than one value.
Note: For clarity, the individual terms of each escape-sequence are
separated by spaces throughout this chapter. When you enter these
commands, you must omit these spaces.
The Variables
N
and n
Many of the Model 880 commands contain variables, represented by
the uppercase letter N or the lowercase letter n. The uppercase letter
N represents an ordinary decimal value, consisting of one or more
numerals. The lowercase letter n represents a single ASCII character
whose value is equivalent to the decimal value from the US ASCII
character table.
The following examples illustrate the use of the variables N and n.
Example 1. Use the escape sequence ESC [ N t to set the form
length to 50 lines.
Escape sequence: ESC [ 5 0 t
Hexadecimal: 1B 5B 35 30 74
In this example, the variable N (50) is represented by the two ASCII
characters 5 and 0. From the US ASCII character table, the hexadecimal
values of these characters are, respectively, 35 and 30. Thus, to set
the value of N to 50, the computer sends the hexadecimal values 35
and 30.
Example 2. Use the escape sequence ESC C n to set the form length
to 50 lines.
Escape sequence: ESC C 2
Hexadecimal: 1B 43 32
