timer |
                 timer, elapsed
              or timer, elapsed, split

         updates the ELAPSED and optionally SPLIT timing arrays.  These
         arrays must each be of type array(double,3); the layout is
         [cpu, system, wall], with all three times measured in seconds.
         ELAPSED is updated to the total times elapsed since this copy
         of Yorick started.  SPLIT is incremented by the difference between
         the new values of ELAPSED and the values of ELAPSED on entry.
         This feature allows for primitive code profiling by keeping
         separate accounting of time usage in several categories, e.g.--
            elapsed= total= cat1= cat2= cat3= array(double, 3);
            timer, elapsed0;
    	elasped= elapsed0;
            ... category 1 code ...
    	timer, elapsed, cat1;
            ... category 2 code ...
    	timer, elapsed, cat2;
            ... category 3 code ...
    	timer, elapsed, cat3;
            ... more category 2 code ...
    	timer, elapsed, cat2;
            timer, elapsed0, total;
         The wall time is not absolutely reliable, owning to possible
         rollover at midnight.

timestamp |
                 timestamp()

         returns string of the form "Sun Jan  3 15:14:13 1988" -- always
         has 24 characters.

transpose |
                 transpose(x)
              or transpose(x, permutation1, permutation2, ...)

         transpose the first and last dimensions of array X.  In the second
         form, each PERMUTATION specifies a simple permutation of the
         dimensions of X.  These permutations are compounded left to right
         to determine the final permutation to be applied to the dimensions
         of X.  Each PERMUTATION is either an integer or a 1D array of
         integers.  A 1D array specifies a cyclic permutation of the
         dimensions as follows: [3, 5, 2] moves the 3rd dimension to the
         5th dimension, the 5th dimension to the 2nd dimension, and the 2nd
         dimension to the 3rd dimension.  Non-positive numbers count from the
         end of the dimension list of X, so that 0 is the final dimension,
         -1 in the next to last, etc.  A scalar PERMUTATION is a shorthand
         for a cyclic permutation of all of the dimensions of X.  The value
         of the scalar is the dimension to which the 1st dimension will move.
         Examples:  Let x have dimsof(x) equal [6, 1,2,3,4,5,6] in order
            to be able to easily identify a dimension by its length. Then:
    	dimsof(x)                          == [6, 1,2,3,4,5,6]
    	dimsof(transpose(x))               == [6, 6,2,3,4,5,1]
            dimsof(transpose(x,[1,2]))         == [6, 2,1,3,4,5,6]
    	dimsof(transpose(x,[1,0]))         == [6, 6,2,3,4,5,1]
    	dimsof(transpose(x,2))             == [6, 6,1,2,3,4,5]
    	dimsof(transpose(x,0))             == [6, 2,3,4,5,6,1]
    	dimsof(transpose(x,3))             == [6, 5,6,1,2,3,4]
    	dimsof(transpose(x,[4,6,3],[2,5])) == [6, 1,5,6,3,2,4]

typeof |
                 typeof(object)

         returns a string describing the type of object.  For the basic
         data types, these are "char", "short", "int", "long", "float",
         "double", "complex", "string", "pointer", "struct_instance",
         "void", "range", "struct_definition", "function", "builtin",
         "stream" (for a binary stream), and "text_stream".
