 Syntax
   func logical islower extern
   param const char cString

 Arguments
   cString is a character string.

   #include example.hdr

   proc Test_islower
   ? islower( "Lloyd Tabb" )             // prints .f.
   ? islower( "lloyd tabb" )             // prints .t.
   ? islower( "   lloyd tabb" )          // prints .f.
   ? islower( "1234 south street" )      // prints .f.
