  9. ;     DESCRIPTION:   This is a header file for handling inclusion of
  10. ;                    "examples" into HTML.
  11. ;
  12. ;                    See PPWIZARD documentation for examples of this file
  13. ;                    in use.  The sample "TryMe.IT" file also uses this
  14. ;                    header file.
  15. ;
  16. ;
  17. ;                    Macro "ExampleFile"
  18. ;                    ~~~~~~~~~~~~~~~~~~~
  19. ;
  20. ;                    This macro takes the following parameters:
  21. ;
  22. ;                         FILE
  23. ;                         ~~~~
  24. ;                         Manditory. Identifies the file to be included.
  25. ;
  26. ;                         FRAGMENT
  27. ;                         ~~~~~~~~
  28. ;                         Optional. You may wish to have a single example
  29. ;                         file hold more than one example.  The text that
  30. ;                         you supply for this parameter marks the line before
  31. ;                         as well as the line after the example.
  32. ;
  33. ;
  34. ;                         INDENT
  35. ;                         ~~~~~~
  36. ;                         Optional.  By default a 4 space indent is used,
  37. ;                         you specify the number of spaces with 0 being
  38. ;                         valid.
  39. ;
  40. ;                         STATE
  41. ;                         ~~~~~
  42. ;                         Optional.  By default no autotagging will be
  43. ;                         performed.  If you specify "REMEMBER" then the
  44. ;                         currently available autotags will be used, you
  45. ;                         may also specify which states tags should come
  46. ;                         from (see the "#AutoTagState +" command).
  47. ;
  48. ;
  49. ;                         ASIS
  50. ;                         ~~~~
  51. ;                         Optional.  By default only basic "AsIs" tagging
  52. ;                         is performed.  If for example you wished to
  53. ;                         handle international characters then you would
  54. ;                         need to specify the names of the AsIs tags to use.
  55. ;
  56. ;
  57. ;
  58. ;                    Macro "Example / eExample"
  59. ;                    ~~~~~~~~~~~~~~~~~~~~~~~~~~
  60. ;
  61. ;                    Note that your "inline" example code is terminated by
  62. ;                    a "eExample" macro where the "Example" part is in the
  63. ;                    EXACT case that you used. This allows the example code
  64. ;                    itself to contain the string "eExample" as long as it
  65. ;                    is in a different case.
  66. ;
  67. ;                    This macro takes the following parameters:
  68. ;
  69. ;
  70. ;                         INDENT
  71. ;                         ~~~~~~
  72. ;                         As above.
  73. ;
  74. ;                         STATE
