  1. a A specially-designed Perl script that can be reused in scripts other than the one for which it was originally intended.
  2. b A compiler directive, used to control the parsing and execution of a Perl script.
  3. c An expression used to help determine the flow of execution, which evaluates as either true or false.
  4. d The first line in every Perl script. Instructs the operating system about the location of the Perl interpreter.
  5. e An ordered list of scalar values.
  6. f The region of code within a program in which a variable or subroutine is accessible.
  7. g A command line interpreter.
  8. h A value that points to another value.
  9. i A language used to create high-performance databases.
  10. j Values passed to a script or program by appending them to the command used to execute the script or program at the command line.
  11. k A numbered value, enclosed in braces, that tells the Perl interpreter which array element to access.
  12. l An operator used to bridge two Boolean expressions to create a single expression.
  13. m A relationship between two objects, in which one object "is" another object.
  14. n A collection of scalar values that can be accessed individually using a key.
  15. o A table of variable names maintained by the Perl interpreter. Organizes code and protects the variables used in one section of a program from being inadvertently overwritten by another section.
  16. p A scripting language that includes some UNIX facilities. It is generally easier to learn and use than other, more structured languages.
  17. q An arbitrary scalar value used to access a hash element.
  18. r An expression resulting in a numerical value as distinct from Boolean expressions.

  28. ab An executable program that accepts the Perl script and executes the instructions contained within it.
  29. ac A data element representing one or more alphanumeric characters.
