Function            isAnarkey - is ANARKEY.COM by Steven Calwas
                                     installed

  Syntax              boolean isAnarkey(void);

  Prototype in        doshk.h

  Remarks             checks if ANARKEY.COM is installed (command line
                      recall programm by Steven Calwas)

  Return value        returns TRUE if Anarkey is installed, FALSE
                      otherwise.

  Note                The default function number used by Anarkey is
                      0xE3. However, the function number used by Anarkey
                      can be changed by the Anarkey user at runtime. This
                      function assumes that the function number used by
                      Anarkey is 0xE3. If Anarkey is using a different
                      function number, isAnarkey() will not perform
                      reliably. Refer to the Anarkey documentation for
                      further details.

  Example             #include <doshk.h>

                      main()
                      {
                           printf("Anarkey is ");
                           if (! isAnarkey())
                                printf("not ");
                           printf("installed\n");
                      }
