edit_times |
                 edit_times, file
              or edit_times, file, keep_list
              or edit_times, file, keep_list, new_times, new_ncycs

         edits the records for FILE.  The KEEP_LIST is a 0-origin index list
         of records to be kept, or nil to keep all records.  The NEW_TIMES
         array is the list of new time values for the (kept) records, and
         the NEW_NCYCS array is the list of new cycle number values for the
         (kept) records.  Either NEW_TIMES, or NEW_NCYCS, or both, may be
         nil to leave the corresponding values unchanged.  If non-nil,
         NEW_TIMES and NEW_NCYCS must have the same length as KEEP_LIST,
         or, if KEEP_LIST is nil, as the original number of records in
         the file.  If KEEP_LIST, NEW_TIME, and NEW_NCYCS are all omitted
         or nil, then edit_times removes records as necessary to ensure
         that the remaining records have monotonically increasing times,
         or, if no times are present, monotonically increasing ncycs.
         (The latest record at any given time/ncyc is retained, and earlier
         records are removed.)
         In no case does edit_times change the FILE itself; only Yorick's
         in-memory model of the file is altered.

eq_nocopy |
                 eq_nocopy, y, x

         is the same as
                y= x
         except that if x is an array, it is not copied, even if it is
         not a temporary (i.e.- an expression).  Having multiple variables
         reference the same data can be confusing, which is why the default
         = operation copies the array.  The most important use of eq_nocopy
         involves pointers or lists:
                y= *py
    	    z= _car(list)
         always causes the data pointed to by py to be copied, while
                eq_nocopy, y, *py
    	    eq_nocopy, z, _car(list)
         does not copy the data - often more nearly what you wanted.
         Note that scalar int, long, and double variables are always copied,
         so you cannot count on eq_nocopy setting up an "equivalence"
         between variables.

error |
                 exit, msg
                 error, msg

         Exits the current interpreted *main* program, printing the MSG.
         (MSG can be omitted to print a default.)
         In the case of exit, the result is equivalent to an immediate
         return from every function in the current calling chain.
         In the case of error, the result is the same as if an error had
         occurred in a compiled routine.

exp |
                 exp(x)

         returns the exponential function of its argument (inverse of log).
