Variables are represented by italicized letters such as n, n1, and m. The variables are explained in the comments section. Note: Some application programs use control key sequences. See the Control Key Chart later in this chapter. Examples The simplest type of command consists of a single character to be sent to the printer. For instance, to print in condensed mode, the code format is: ASCII code: SI Decimal: 15 Hexadecimal: OF This code can be sent from a program by sending the code 15 directly. More complex commands consist of two or more character codes. For example, to print in double-wide mode, the code format is the following: ASCII code: ESC W n Decimal: 27 87 n Hexadecimal: 1B 57 n In this case n can be either 1 (on) or 0 (off), to begin or end doublewide printing. You can use either of the following commands to turn on double-wide print from BASIC: LPRINT CHR$(27);CHR$(87);CHR$(1) LPRINT CHR$(27);"W";CHR$(1) For the following commands that use only 0 or 1 for the variable, either the decimal or hexadecimal values 1 and 0 or the ASCII characters 1 and 0 can be used: ESC U, ESC x, ESC p, ESC W, ESC S, ESC-, ESC %, and ESC w. 9-4 Command Summary
