The following functions are used to handle strings, using prefix syntax:
String literals: single-line and multiline strings
String literals are used to represent and manipulate data as a sequence of characters. For example, string literals can be used to display information, define a constant, etc.

Middle (Function)
Extracts:
  • a substring from a string starting at a specified position.
  • part of a buffer starting at a specified position.
