Tcl "lcompare" command…

[Tom Rioux]

Has anyone used this command?   I don’t see a man page for it anywhere.  I have it some code I am testing but I am getting mixed results.   It is returning either a -1, 0, or 1 and I’m sometimes I’m seeing a 1 or 0 when I expect a -1.

Any information would be helpful.

Thanks….

It comes from an old extended Tcl library.  From a hcitcl/tcl prompt

     

   tcl> help hci/lists/lcompare

   lcompare list1 list2

       This   command compares two lists   and returns thier relation

       (like strcmp 0).   Corresponding elements of each list

       are compared.  The result is the value of the first difference

       encountered or equality.  A list that is a prefix of the other

       list   is   considered   to  be  less  than  the  other  list.

       By default, items are compared lexicographically. The -numeric

       flag (or some unique fraction thereof),  however,  causes  the

       items  to  be  compared  as  double-precision   floating-point

       numbers.
