*DEFINE BUTTON INTRO.BMP
  "CONTENTS"
  "Introduction and references"
  "This button allows you to display an introduction to the package, or a list
  of references."

*DEFINE BUTTON SPACE

*DEFINE BUTTON /S RESTARTvi.BMP
  "RESTART"
  "Start a new identification" 
  "This button starts a new identification."

*DEFINE BUTTON /-S RESTARTvi.BMP
  "RESTART"
  "Start a new identification or query" 
  "This button clears the information entered about the `specimen'. It is used
  to start a new identification or query."

*DEFINE BUTTON BEST.BMP
  "BEST"
  "Continue identification, using 'best' characters"
  "This button finds and displays the best characters for separating
  the remaining taxa in an identification. A character or characters may be
  selected from the display, and used to enter information about the specimen
  being identified.
  [1p] The merit of a character is calculated partly from its separating power,
  and partly from its `reliability' or ease of use. Characters are displayed in
  order of merit, and their separating powers are shown at the left of the
  display. A separating power of 1 corresponds to a division of the group of
  remaining taxa into halves, and a value of 0 indicates very poor separation.

*DEFINE BUTTON /U CHANGE.BMP
  "CHANGE ?L"
  "Change previously entered information about the specimen being identified"
  "This button allows you to change previously entered information
  about the specimen being identified."

*DEFINE BUTTON SPACE

*DEFINE BUTTON DESC.BMP
  "DESCRIBE ?L ALL"
  "Display complete descriptions of selected taxa"
  "This button allows you to display full descriptions of any taxa. You can also
  display the information which you have entered about the specimen being
  identified."

*DEFINE BUTTON DESC_S.BMP
  "DESCRIBE ?L BRIEF"
  "Display nomenclature, classification, etc. for selected taxa"
  "This button allows you to display, for selected taxa, a brief description
  containing nomenclature, classification, number of species, geographical
  distribution, and references."

*DEFINE BUTTON /U DIFF.BMP
  "DIFFERENCES (SPECIMEN REMAINING) ALL"
  "Display the differences between the specimen and the remaining taxon"
  "A number in parentheses preceding the name of the remaining taxon in an
  identification indicates the number of differences between the specimen and
  the taxon. This button can be used to find the characters in which these
  differences occurred."

*DEFINE BUTTON SPACE

*DEFINE BUTTON ILL_T.BMP
  "ILLUSTRATE TAXA REMAINING"
  "Display illustrations of the remaining taxa"
  "This button displays illustrations of the remaining taxon or taxa in an
  identification. You can use it to confirm an identification, or to complete an
  identification by browsing through the illustrations of the remaining taxa."

*DEFINE BUTTON SPACE

*DEFINE BUTTON SET_TOL.BMP
  "SET TOLERANCE"
  "Set the error tolerance"
  "This button allows you to set the `error tolerance' for an identification. A
  taxon will remain under consideration until the number of differences between
  it and the specimen is greater than the error tolerance. You should increase
  the current value by 1 if you are aware that you have made a mistake in an
  identification (because the illustration or description of the remaining taxon
  does not correspond to your specimen), but you do not know what the mistake
  is."

*DEFINE BUTTON /-S SET_ID.BMP
  "SET MATCH O I U"
  "Set parameters for identification"
  "This button sets the `Match' parameter (see Settings/Set/Match) to the
  values recommended for routine identification."

*DEFINE BUTTON /-S SET_IR.BMP
  "SET MATCH O"
  "Set parameters for information retrieval"
  "This button sets the `Match' parameter (see Settings/Set/Match) to the
  values recommended for routine information retrieval."

*DEFINE BUTTON INC_C.BMP
  "INCLUDE C ?K"
  "Select subsets of the characters"
  "This button allows you to choose a set of characters with which all
  subsequent
  commands operate. Note that it is not usually necessary to do this if the
  set of characters is to be used only for a single command, as most commands
  have a built-in character-selection dialog box. See Settings/Include for
  more details."

*DEFINE BUTTON INC_T.BMP
  "INCLUDE T ?K"
  "Select subsets of the taxa"
  "This button allows you to choose a set of taxa with which all subsequent
  commands operate. Note that it is not usually necessary to do this if the
  set of taxa is to be used only for a single command, as most commands
  have a built-in taxon-selection dialog box. See Settings/Include for
  more details.

*DEFINE BUTTON INC_T_A.BMP
  "INCLUDE T ALL"
  "Include all taxa"
  "This button allows subsequent commands to operate on all levels of taxa."

*DEFINE BUTTON INC_T_F1.BMP

  "Include only families"
  "This button restricts subsequent operations to families."

*DEFINE BUTTON INC_T_G1.BMP
