Using the Command Summary

Each command description has a format section and a comment section, The format section gives the ASCII, decimal, and hexadecimal values for the command. These three formats are equivalent, and it should be easy to pick the one most suited to your purpose. The comment section describes the effect of the command and gives any additional information necessary for using it.

Note: Some application programs can use control key sequences. See the Control key chart on page 9-4 for information on using control keys.

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

H e x a d e c i m a l : O F

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 or 0, to begin or end double-wide printing. You can use either of the following commands to turn on double-wide printing from BASIC:

LPRINT CHR$(27):CIiR$(87):CHR$tl)

LPRINT CHR$(27):"W":CHR$(l)
