                 has_records(file)

         returns 1 if FILE has history records, 0 if it does not.

    interpreted function, defined at i0/std.i   line 2392
help |
                 help, topic
              or help

         Prints DOCUMENT comment from include file in which the variable
         TOPIC was defined, followed by the line number and filename.
         By opening the file with a text editor, you may be able to find
         out more, especially if no DOCUMENT comment was found.
         Examples:
           help, set_path
         prints the documentation for the set_path function.
           help
         prints the DOCUMENT comment you are reading.
         This copy of Yorick was launched from the directory:
         **** Y_LAUNCH (computed at runtime) ****
         Yorick's "site directory" at this site is:
         **** Y_SITE (computed at runtime) ****
         You can find out a great deal more about Yorick by browsing
         through these directories.  Begin with the site directory,
         and pay careful attention to the subdirectories doc/ (which
         contains documentation relating to Yorick), and i/ and
         contrib/ (which contain many examples of Yorick programs).
         Look for files called README (or something similar) in any
         of these directories -- they are intended to assist browsers.
         The site directory itself contains std.i and graph.i, which
         are worth reading.
         Type:
           help, dbexit
         for help on debug mode.  If your prompt is "dbug>" instead of
         ">", dbexit will return you to normal mode.
         Type:
           quit
         to quit Yorick.

histogram |
                 histogram(list)
              or histogram(list, weight)

         returns an array hist which counts the number of occurrences of each
         element of the input index LIST, which must consist of positive
         integers (1-origin index values into the result array):
              histogram(list)(i) = number of occurrences of i in LIST
         A second argument WEIGHT must have the same shape as LIST; the result
         will be the sum of WEIGHT:
              histogram(list)(i) = sum of all WEIGHT(j) where LIST(j)==i
         The result of the single argument call will be of type long; the
         result of the two argument call will be of type double (WEIGHT is
         promoted to that type).  The input argument(s) may have any number
         of dimensions; the result is always 1-D.
       KEYWORD: top=max_list_value
         By default, the length of the result is max(LIST).  You may
         specify that the result have a larger length by means of the TOP
         keyword.  (Elements beyond max(LIST) will be 0, of course.)
