  1. a An expression resulting in a numerical value as
    distinct from Boolean expressions.
  2. b Pattern Found
  3. c Equal to
  4. d Identify loops so the user can utilize loop-control commands.
  5. e Used in conjunction with a loop label to achieve a more specialized functionality. Commands are: last, next, and redo.
  6. f A mechanism by which the command line can be used to redirect input to, or output from, a script.
  7. g Less than or equal to
  8. h Numbered value, enclosed in braces [] that tells the Perl interpreter which array element to access.
  9. i variable defined by a single, discreet value. Includes numbers and strings. Begins with a $ sign.
  10. j A special sequence of characters used to represent a
    nonprintable ASCII character or other character that, if
    used alone, has some significance within a programming
    language or expression.
  11. k Less than
  12. l Any character that would, in local character set, act as the limits for a word. This would include space and punctuation but exclude hyphens and underscores.
  13. m Loop-Control Command: Exits the loop entirely
  14. n $input = <STDIN>;
    print($input);
  15. o Greater than or equal to
  16. p Strips the new-line character from the end of a
    string.
  17. q Pattern not found
  18. r Loop-Control Command: Interrupts the current iteration through the loop and proceeds directly to the next iteration.
  19. s Code which indicates a list of characters that one element is a string will match. A negative character class is one in which the element in a string does not match any character in the list.
  20. t An input/output connection between the program and a particular file or device.
  21. u An expression used to match patterns within a string. Can be literal strings or complex patterns created using special characters and modifiers.
  22. v Defines a block of code that will execute repeatedly (loop) as long as some Boolean expression evaluates as true. If the expression is false, the block of code will not execute.
  23. w An operator used to bridge two Boolean expressions to create a single expression.
  24. x Special Character used to create a complex pattern.
  25. y nonprintable characters, or characters that have special meaning in Perl code. All start with a backward slash.
  26. z A common data structure that operates under LIFO
    (last in, first out) rules.
  27. aa Not equal to
  28. ab The first line in every Perl script that instructs the operating system about the location of the Perl interpreter.
  29. ac Defines a block of code that will execute repeatedly (loop) as long as some Boolean expression evaluates as true. Does not evaluate the condition until after the code block has been executed.
  30. ad Greater than
  31. ae Practical Extracting and Reporting Language
  32. af statement that assigns a value to a variable.
  33. ag Loop-Control Command: Restarts the code block without evaluating any Boolean expression set as conditions.
  34. ah Operator applies one value as the exponent of another. 2**3 which is the equivalent as 2^3 power.
  35. ai assignment statement
  36. aj Common data structure that operates under FFIO (First in, First Out) rules.
  37. ak Simplest control structure that defines a block of code that executed only if a Boolean condition evaluates to TRUE. Curly brackets are required.
  38. al Rule that governs how a variable may start
  39. am Variables that operate the same manner as variables in algebraic functions.
  40. an A mechanism to retrieve data from the user while a script is executing.
  41. ao Three expressions separated by semicolons. The initialization expression is typically used to initialize a variable to be used as a counter. The Boolean expression is the condition on which the loop will be exited. The increment expression is executed at the end of each code block, and is typically used to increment the counter variable in some way.
  42. ap The default output stream provided by
    the operating system. Text output
    to standard out may be directed to a
    terminal window, a file, a printer, or
    other output device.
  43. aq . is used to concatenate strings.
  44. ar Variant form to a Do{}While loop.
  45. as Defines a code block that will be executed repeatedly until some Boolean expression evaluates as true.
  46. at An expression used to help determine the flow of execution, which evaluates as either true or false.
