Format For Control Code Descriptions
The following information is listed for each control code (where a pplicable):
Name The title or function of the command.
ASCII Code The ASCII mnemonic for the command is shown for the prin ter
and the ANSI protocol. Command sequences are in 7-bit (ASCII)
form.
Hex Code The code or command sequence in hexadecimal numbers.
Dec Code The code or command sequence in decimal numbers.
Expression The control codes used in the BASIC programming language.
Purpose The function(s) of the control code.
Discussion A discussion of the uses of the code or command sequence,
including exceptions or limitations to its use.
Example A sample program written in BASIC programming language is
provided when it is possible to illustrate the effect of a control
code or if a specific syntax is required.
Examples are shown below of escape sequences as written in the text, shown
with parameters filled in, and written in the BASIC program language.
Tab Clear ESC [p1 g
ESC[3g
LPRINT CHR$(27);“[3g”
Horizontal Tabs Set ESC [p1;p2...pn u
ESC[648;1386;2808u

NOTE: If you specify parameters for a control code other than the ones
defined in the control code description, unpredictable results may
occur.
