Generally, extracting substrings in Ecstasy is most easily performed using the slice operator, but there is also a <code>substring()</code> method:
<syntaxhighlight lang="ecstasy">
module Substrings {
void run(String[] args = []) {
String s = args.size > 0 ? args[0] : "hello";
@Inject Console console;
console.print(
$|Original : { s .quoted()=}
|Remove first: { s.substring(1) .quoted()=}
|Remove first: {(s.size < 1 ? "" : s[1..<s.size ]).quoted()=}
|Remove last : {(s.size < 1 ? "" : s[0..<s.size-1]).quoted()=}
|Remove both : {(s.size < 2 ? "" : s[1..<s.size-1]).quoted()=}
);
}
}
</syntaxhighlight>

x$ xec Substrings
Original : s .quoted()="hello"
Remove first: s.substring(1) .quoted()="ello"
Remove first: (s.size < 1 ? "" : s[1..<s.size ]).quoted()="ello"
Remove last : (s.size < 1 ? "" : s[0..<s.size-1]).quoted()="hell"
Remove both : (s.size < 2 ? "" : s[1..<s.size-1]).quoted()="ell"
x$ xec Substrings a
Original : s .quoted()="a"
Remove first: s.substring(1) .quoted()=""
Remove first: (s.size < 1 ? "" : s[1..<s.size ]).quoted()=""
Remove last : (s.size < 1 ? "" : s[0..<s.size-1]).quoted()=""
Remove both : (s.size < 2 ? "" : s[1..<s.size-1]).quoted()=""
x$ xec Substrings ab
Original : s .quoted()="ab"
Remove first: s.substring(1) .quoted()="b"
Remove first: (s.size < 1 ? "" : s[1..<s.size ]).quoted()="b"
Remove last : (s.size < 1 ? "" : s[0..<s.size-1]).quoted()="a"
Remove both : (s.size < 2 ? "" : s[1..<s.size-1]).quoted()=""
x$ xec Substrings abc
Original : s .quoted()="abc"
Remove first: s.substring(1) .quoted()="bc"
Remove first: (s.size < 1 ? "" : s[1..<s.size ]).quoted()="bc"
Remove last : (s.size < 1 ? "" : s[0..<s.size-1]).quoted()="ab"

=={{header|RPL}}==
Basic RPL:
"Knight" 2 OVER SIZE SUB
"Socks" 1 OVER SIZE 1 - SUB
"Brooms" 2 OVER SIZE 1 - SUB
From HP-48 versions, one can also do this way:
"Knight" TAIL
"Socks" REVLIST TAIL REVLIST
"Brooms" TAIL REVLIST TAIL REVLIST

{{libheader|Wren-str}}
As Wren's string slicing and other built-in methods generally work at the byte level, we use the above module for this task which works at the code-point level.
