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
