Occasionally, you need to specify various special characters. You can
specify the space character, straightforwardly, as $ .
Alternatively, you can specify the space character, and several others, by
accessing the CharacterConstants dictionary with various
strings:
| String | Character value | |||
'Space' | space | |||
'Tab' | tab | |||
'Cr' | carriage return | |||
'Lf' | line feed | |||
'Ff' | form feed | |||
'Bs' | backspace | |||
For example, if you need the tab character, you can fetch it from
the CharacterConstants dictionary via the following
expression:
CharacterConstants at: 'Tab'
