DETERMINING THE USER SELECTION(S)

     There are three global variables declared in the interface section of
     the ListTTT5 unit that are used to determine the option(s) that a user
     selected:

     L_Pick - this byte variable indicates the highlighted topic, i.e. the
     string array number, when the Esc or End_Chars key was pressed.

     L_Char - this is the key that the user pressed to terminate the list
     session. It must be either #027 (if AllowEsc is true) or one of the
     End_Chars keys.

     L_Picks - this is defined as an array[1..Max_Topics] of boolean. If
     AllowToggle is true, the user can select more than one topic. Each
     selected topic will have the equivalent L_Picks element set to true.
     Note: L_Pick still indicates the highlighted topic.
