String#
Introduction#
A String is an immutable sequence of 16 bit characters that is usually used to represent text.
String literals are sequences of characters enclosed in "
(quotation marks / doublequote).
String literals may also include escape sequences, special sequences of characters used to represent unprintable characters.
Escape characters#
You can use the following escape sequences in string literals:
Escape sequence | Character code |
---|---|
~q | 34 (quotation mark ") |
~n | 10 (newline) |
~r | 13 (return) |
~t | 9 (tab) |
~z | 0 (null) |
~~ | 126 (tilde ~) |
"" |
34 (double-doublequote, same as ~q ) |
For example, to include literal quotation marks in a string:
Local test1 := "~qHello World~q"
Local test2 := "Using "" inside strings"
Strings can also be declared across multiple lines:
Const multiLine := "
Multi Line String
"
In this case, each newline inside the quote marks is simply included in the string, so the above example string actually contains 2 'hidden' newlines.
String variables are declared using the type name String
, for example:
Local test:String = "Hello World"
You can index a string using the []
operator:
Local str := "Hello World"
For Local i := 0 Until str.Length
Print str[i]
Next
Indexing a string will return the character code at a given string index as an int.
You can iterate through the characters in a string using Eachin
:
For Local chr := Eachin "Hello World"
Print chr
Next
