A control sequence, also known as escape sequence, is a series of characters used for controlling console text output. When a control sequence is printed to a console window, text style or colors change. There are also control sequences for moving the cursor, erasing characters, clearing the console window, scrolling the console window content, and more.
−
If an item is enclosed in square brackets, it is optional and may be omitted. For example, for '''Insert [N] Characters''' the value for '''N''' is shown as optional. The console device responds to such optional items by treating the value of '''N''' as 1 if it is not specified. The value of '''N''' or '''M''' is always a decimal number, having one or more ASCII digits to express its value.
  
  +
  +
The length of a control sequence varies from a single character to four character sequences. Some of the longer sequences contain one or two numeric parameters, which for example allow you to move the cursor for a supplied number of steps.
  +
  +
The parameters are marked in the sequence with letters '''N''' and '''M''', and they are expected to be replaced with a decimal number when the sequence is used. If '''N''' or '''M''' is enclosed in brackets, the parameter is optional and can be omitted. When the parameter is left out, the console uses a default value of 1.
  +
  +
{{Note|Parameters must be inserted in the control sequence as ASCII digits and not as hexadecimal numbers.}}
  +
For example to move the cursor forward 15 positions, the control sequence string ('''cs_cursor_fw''') must be constructed as follows:
  +
<syntaxhighlight lang="rexx">
  +
cs_cursor_fw = '9b'x || '15' || '43'x
  +
</syntaxhighlight>
  +
'''9B''' and '''43''' are hexadecimal values and '''15''' is an ASCII string.
  +
When the control sequence string is printed to the console, the cursor moves forward 15 positions:
  +
<syntaxhighlight lang="rexx">
  +
SAY cs_cursor_fw || 'Hello!'
  +
</syntaxhighlight>

These control sequences allow you to move the cursor, erase characters, scroll the console window, control word wrapping, set console marginals, flash the screen, select graphic character set, set cursor properties, and change the line feed mode.

These control sequences allow you to change text style and colors.

The available text styles are: plain, bold, italic, underscore, strike-through, reverse video, faint, blinking, and concealed. Styles can be mixed, i.e. you can print bold italic text or reverse video italic text, etc.

Character color (foreground color), character cell color (text background color) and console background color can be selected freely from an 8 pen palette. The palette pen colors can be changed through the '''Console Preferences Editor'''. See [[AmigaOS Manual:Console Preferences Editor|Console Preferences Editor]] for more information on the console colors.

A control sequence, also known as escape sequence, is a series of characters used for controlling console text output. When a control sequence is printed to a console window, text style or colors change. There are also control sequences for moving the cursor, erasing characters, clearing the console window, scrolling the console window content, and more.

The length of a control sequence varies from a single character to four character sequences. Some of the longer sequences contain one or two numeric parameters, which for example allow you to move the cursor for a supplied number of steps.

The parameters are marked in the sequence with letters N and M, and they are expected to be replaced with a decimal number when the sequence is used. If N or M is enclosed in brackets, the parameter is optional and can be omitted. When the parameter is left out, the console uses a default value of 1.

Note
Parameters must be inserted in the control sequence as ASCII digits and not as hexadecimal numbers.

For example to move the cursor forward 15 positions, the control sequence string (cs_cursor_fw) must be constructed as follows: 

cs_cursor_fw = '9b'x || '15' || '43'x

9B and 43 are hexadecimal values and 15 is an ASCII string. When the control sequence string is printed to the console, the cursor moves forward 15 positions: 

SAY cs_cursor_fw || 'Hello!'

Console Control Sequences

These control sequences allow you to move the cursor, erase characters, scroll the console window, control word wrapping, set console marginals, flash the screen, select graphic character set, set cursor properties, and change the line feed mode.

Command Comment Sequence of Characters (in Hexadecimal Form)
Bell Flash the display 07
Backspace Move cursor left one column 08
Horizontal Tab Move cursor right one tab stop 09
Line Feed Move cursor down one text line 0A
Vertical Tab Move cursor up one text line 0B
Form Feed Clear the console’s window 0C
Carriage Return Move cursor to the first column 0D
Shift In Use ASCII graphic characters 0E
Shift Out Use ECMA 94 Latin 1 graphic characters 0F
Esc Escape 1B
Index Move the active position down one line 84
Next Line Go to the beginning of the next line 85
Horizontal Tabulation Set a tab at the active cursor position 88
Reverse Index Move the active position up one line 8D
CSI Control sequence introducer 9B
Reset to defaults Reset console to Initial State 1B 63
Insert [N] Characters Insert one or more spaces, shifting the remainder of the line to the right 9B [N] 40
Cursor On Show cursor 9B 20 70
Cursor Off Hide cursor 9B 30 20 70
Cursor Up [N] Positions Move cursor up [N] character positions. Default is 1. 9B [N] 41
Cursor Down [N] Positions Move cursor down [N] character positions. Default is 1. 9B [N] 42
Cursor Forward [N] Positions Move cursor forward [N] character positions. Default is 1. 9B [N] 43
Cursor Backward [N] Positions Move cursor backward [N] character positions. Default is 1. 9B [N] 44
Set Cursor Position Where [N] is row, [M] is column, and semicolon (hex 3B) must be present as a separator, or if row is left out, so the console device can tell that the number after the semicolon actually represents the column number. 9B [N] [3B M] 48
Cursor Horizontal Tabulation Move cursor forward [N] tab positions. 9B [N] 49
Cursor Next Line [N] Move cursor [N] lines down. Cursor column is set to 1. 9B [N] 45
Cursor Preceding Line [N] Move cursor [N] lines up. Cursor column is set to 1. 9B [N] 46
Erase in Display Clear at end of the display starting from the current cursor position. 9B 4A
Erase in Line Clear at the end of the line starting from the current cursor position. 9B 4B
Insert Line Insert a line above the line containing the cursor. 9B 4C
Delete Line Remove the current line, move all lines up one position to fill gap, and blank the bottom line. 9B 4D
Delete Character [N] Delete the character that the cursor is sitting on and [N] characters to the right of the cursor. 9B [N] 50
Scroll up [N] Lines Remove line(s) from the top of the console window, move all other lines up, and blank [N] bottom lines. 9B [N] 53
Scroll down [N] Lines Remove line(s) from the bottom of the console window, move all other lines down, and blank [N] top lines. 9B [N] 54
Cursor Tabulation Control Controls the cursor tabulation: when [N] = 0, set tab; when [N] = 2, clear tab; and when [N] = 5, clear all tabs. 9B [N] 57
Cursor Backward Tabulation Move cursor backward [N] tab positions. 9B [N] 5A
Set Line Feed Mode Cause Line Feed to respond as Return + Line Feed. 9B 32 30 68
Reset Newline Mode Cause Line Feed to respond only as Line Feed. 9B 32 30 6C
Enable Scroll Enable scrolling. This is the default setting. 9B 3E 31 68
Disable Scroll Disable scrolling 9B 3E 31 6C
Autowrap On Enable word wrapping. This is the default setting. 9B 3F 37 68
Autowrap Off Disable word wrapping 9B 3F 37 6C
Set Page Length to N In character raster lines, causes console to recalculate, using current font, how many text lines will fit on the page 9B N 74
Set Line Length to N In character positions, using current font, how many characters should be placed on each line 9B N 75
Set Left Offset to N In raster columns, how far from the left of the window should the text begin 9B N 78
Set Top Offset to N In raster lines, how far from the top of the window’s RastPort should the topmost line of the character begin 9B N 79

Graphic Rendition Control Sequences

These control sequences allow you to change text style and colors.

The available text styles are: plain, bold, italic, underscore, strike-through, reverse video, faint, blinking, and concealed. Styles can be mixed, i.e. you can print bold italic text or reverse video italic text, etc.

Character color (foreground color), character cell color (text background color) and console background color can be selected freely from an 8 pen palette. The palette pen colors can be changed through the Console Preferences Editor. See Console Preferences Editor for more information on the console colors.
